El largo de un rectángulo es 8 metros mayor que su ancho. Si el ancho del rectángulo es x metros, la expresión algebraica que representa su perímetro es: *
Answer:
La expresión algebraica que representa el perímetro del rectángulo es:
perímetro = 4x + 16
Step-by-step explanation:
La formula del perímetro de un rectángulo es:
p = 2(ancho + largo)
Entonces:
b = x + 8 primer ecuación
p = 2(x+b) segunda ecuación
x = longitud del ancho del rectángulo
b = longitud del largo del rectángulo
por tanto:
sustituyendo el valor de la primer ecuación en la segunda ecuación:
p = 2(x + (x+8))
p = 2(2x + 8)
p = 4x + 16
Usando conceptos de rectángulo, se encuentra que el perímetro está dado por:
[tex]P = 4x + 16[/tex]
El perímetro de un rectangulo de ancho a y largo l es dado por:
[tex]P = 2(l + a)[/tex]
En este problema, el ancho es de x metros, o sea, [tex]l = x[/tex], enquanto el largo 8 metros mayor que su ancho, o sea, [tex]l = x + 8[/tex]
Por eso, el perímetro es dado por:
[tex]P = 2(l + a)[/tex]
[tex]P = 2(x + x + 8)[/tex]
[tex]P = 2(2x + 8)[/tex]
[tex]P = 4x + 16[/tex]

Answer:
The parts are 24 and 16
Step-by-step explanation:
Let's call the two parts x and y. We can write the following system:
x + y = 40 -- Equation 1
1/4x = 3/8y -- Equation 2
2x = 3y -- Equation 3 (Multiply Equation 2 by 8 to get rid of denominators)
2x + 2y = 80 -- Equation 4 (Multiply Equation 1 by 2)
3y + 2y = 80 -- (Substitute 2x = 3y into Equation 4)
5y = 80 -- (3y + 2y = 5y)
y = 16 -- (Divide by 5)
x + 16 = 40 -- (Substitute y = 16 into Equation 1)
x = 24 -- (Subtract 16)

ANSWER FOR 30 POINTS A 13-foot ladder is leaning against a tree. The bottom of the ladder is 5 feet away from the bottom of the tree. Approximately how high up the tree does the top of the ladder reach?
Answer:
12 feet
Step-by-step explanation:
Use the Pythagorean Theorem to find how high up the tree the top of the ladder reaches.
13 feet - hypotenuse
5 feet - can be a or b
a² + b² = c²
5² + b² = 13²
25 + b² = 169
b² = 144
b = √144
b = 12
The top of the ladder reaches 12 feet up the tree.
Hope that helps.
Answer:
12 ft
Step-by-step explanation:
These circumstances describe a triangle with hypotenuse 13 ft and bottom side 5 ft. The vertical side (height above ground to top of ladder) is to be found. According to the Pythagorean Theorem,
5^2 + (vertical side)^2 = 13 ft = 169, and so
(vertical side) = sqrt( 169 - 25 ) = 144 (ft)
The top of the ladder is s 12 ft above the ground.

Answer:
f(x) = 2(x –3)²
Step-by-step explanation:
f(x) = 2x² – 12x + 18
The vertex form of the above expression can be obtained as follow:
f(x) = 2x² – 12x + 18
Factorise
f(x) = 2(x² – 6x + 9)
Next, we shall simplify x² – 6x + 9 by factorisation method.
This is illustrated below:
x² – 6x + 9
Multiply the first term i.e x² and last term i.e 9 together. The result is 9x².
Next, find two factors of 9x² such that their sum will result to the 2nd term i.e –6x in the expression above.
The factors are –3x and –3x
Next, replace –6x with –3x and –3x in the equation above as shown below:
x² – 6x + 9
x² – 3x –3x + 9
Factorise
x(x – 3) –3(x –3)
(x –3)(x –3)
(x –3)²
f(x) = 2x² – 12x + 18
f(x) = 2(x² – 6x + 9)
f(x) = 2(x –3)²
Therefore, the vertex form of the function f(x) = 2x² – 12x + 18 is
f(x) = 2(x –3)²
Brock wants to compete for the featherweight boxing title, but the upper limit for that weight class is 126 pounds. He currently weighs 134 pounds. Brock can lose 3 pounds per day if he does vigorous workouts. The number of days, d, that Brock will need to work out to compete at the featherweight level is represented by the inequality 134 – 3d < 126. Select the fewest number of days he would have to work out to compete at the featherweight level. A. 1 B. 2 C. 3 D. 4 E. 5
Answer:
C. 3
Step-by-step explanation:
Brock weighs 134 pounds, he will lose 3 pounds a day until he is 126 pounds
D will represent the number of days he will work out.
134 - 3d < 126
134 - 3(3) < 126
134 - 9 = 125
125 < 126
3 days
We can say that Brock needs to workout for minimum 3 days to compete at feather weight level.

Answer:
a. True, because they are corresponding angles.
b. False, because angles 1 and 2 are supplementary, meaning that they add up to 180 degrees, but 125 + 65 = 190 degrees.
c. True, because they are corresponding angles.
d. True, becuase they are two angles that add up to 180 degrees.
e. True, because they are both interior angles on opposite sides of the transversal.
Answer:
a. True.
b. False.
c. True.
d. True.
e. True.
Step-by-step explanation:
a. This statement is true because angles 6 and 8 are vertical angles. That means they are congruent.
b. This statement is false because Elm Street is a straight line, which means that angles 1 and 2 are supplementary angles and their measures will add up to be 180 degrees. 65 + 125 = 190, which is not equal to 180.
c. This statement is true because angles 5 and 1 correspond to each other.
d. This statement is true because angles 7 and 8 form a straight line.
e. This statement is true because they are interior angles that are alternate.

Make x the subject of the formula y = m x − c
Answer:
y + c ÷ m = x
Step-by-step explanation:
You start of with:
y = mx - c
We can get rid of the + c by putting it on the other side. When a number goes to the other side it does the opposite, so the - will become a +. It will end up as:
y + c = mx
We just need x on itself so we need to get ride of m. In this sum, mx means that they are multiplying together, we need to make that divide. So we take m on the other side and make it divide. This brings us to x on itself.
(y+c) ÷ m = x
Hope this helps.
x can be changed into the subject of the formula as x = (y + c) / m.
What is an Equation?An equation is the statement of two expressions located on two sides connected with an equal to sign. The two sides of an equation is usually called as left hand side and right hand side.
Subject of an equation is that variable we are going to find out.
The given equation is y = mx - c.
Here y is the subject.
We need to rewrite the equation to make x the subject.
y = mx - c
Adding c on both sides,
y + c = mx - c + c
y + c = mx
Dividing both sides by m, we get,
(y + c) / m = mx / m
(y + c) / m = x
Hence the given formula y = mx - c can be rewritten to make x the subject as x = (y + c) / m.

Aiko is finding the sum (4 + 5i) + (–3 + 7i). She rewrites the sum as (–3 + 7)i + (4 + 5)i. Which statement explains the error Aiko made by using a mathematical property incorrectly?
Answer:
The error was made when they factored out the i, so this would be the distributive property they did not do correctly.
Factoring out the i was never needed.
Answer:
She shouldn't have factored out the i.
Step-by-step explanation:
In both parentheses, only one of the two additives had an "i" in it, so only one of them could have i factored out of it. If she wanted to factor out the i, the equation would look like this:
(4/i + 5)i + (-3/i + 7)i.
If anything, she should have done:
5i+7i + 4-3=
12i + 1.
Factoring out the i was unnecessary.

A farmer uses 3/5 of his land to grow cassava, 1/3 of the remainder for yam and the rest for maize. Find the part of the land used for maize
Answer:
Step-by-step explanation:
Cassava = 1/3 of his land
Remaining after planting Cassava = 1 - 1/3 = 2/3 of his land
Maize = 2/5 x 2/3 = 4/15 of his land
Vegetables = 2/3 - 4/15 = 2/5 of his land
If vegetables = 10 acres
2/5 of his land = 10 acres
1/5 of his land = 10 ÷ 2 = 5 acres
5/5 of his land = 5 x 5 = 25 acres

The number of times the die was rolled is obtainable by adding all the frequencies ;
That would be ;
3 + 6 + 8 + 11 + 14 + 16 + 15 + 12 + 9 + 5 + 1 = 100
Now let’s add the frequencies of results which are less than 10;
That would be the frequencies of the numbers 2-9;
Thus, we have;
3 + 6 + 8 + 11 + 14 + 16 + 15 + 12 = 85
