Answer:
A) A = 4x^2 - x - 5
B) f(2) = 9
Step-by-step explanation:
area is L x W, so you multiply 4x - 5 with x + 1
A = (4x - 5)(x + 1)
which gives you
A = 4x^2 - x - 5
you would then plug in 2 for x which gives you your answer of
9
Hope this helps you :)
What is the GCF for 4x^2yz^3 and 12xz^2
Answer:
The great common factor is:
x(2z)²Steps:
given:
4x²yz³12xz²4x²yz³ = 2²x²z²yz
4x²yz³ = x(2z)²xyz
---------------------------------
12xz² = 4×3xz²
12xz² = 2²3xz²
12xz² = x(2z)²3
The great common factor is: x(2z)²
Answer:
4xz^2.
Step-by-step explanation:
GCF of 4 and 12 is 4
GCF of x^2 and x is x.
GCF of z^3 and z^2 is z^2.
Find the value of x in the isosceles triangle shown below.
Answer:
B
Step-by-step explanation:
Since the triangle is isosceles, then the segment from the vertex is a perpendicular bisector and the triangle is divided into 2 right angles with legs 12 and [tex]\frac{1}{2}[/tex] x with hypotenuse 15
Using Pythagoras' identity in the right triangle
( [tex]\frac{1}{2}[/tex] x )² + 12² = 15²
[tex]\frac{1}{4}[/tex] x² + 144 = 225 ( subtract 144 from both sides )
[tex]\frac{1}{4}[/tex] x² = 81 ( multiply both sides by 4 to clear the fraction )
x² = 324 ( take the square root of both sides )
x = [tex]\sqrt{324}[/tex] = 18 → B

Answer:
175 ft
Step-by-step explanation:
From the question,
(a) ΔABC and ΔEDC are similar because all the angles in ΔABC is equal to the corresponding angles in ΔEDC.
I.e, ΔABC is equiangular to ΔEDC. (AAA).
(b) From the diagram.
for similar angle, ratio of corresponding sides are equal

The shape of Joy’s room is a rectangle 540 cm long by 250 cm wide.
a. Work out the area of his room in Square meters.
b. How much does he pay to buy flooring for his room where flooring costs $ 40 per square meter
Question No. aWork out the area of his room in Square meters.
Given:-Length of the room 540 cm = 540/100 m = 5.4mBreadth of the room 250cm = 250/100 m = 2.5mTo Find:-Area of the room. Solution:-We know that:-
Area of a rectangle = (length × breadth)sq.units
Therefore,
Area of the rectangular room = (5.4 × 2.5) square meters
=> Area of the rectangular room = 13.5 square meters.
Answer:-Area of his room is 13.5 square meters.
Question No. bHow much does he pay to buy flooring for his room where flooring costs $ 40 per square meter
Given:-Cost in per square meter = $40Area of the room = 13.5 square meters (From question a) To Find:-Total cost of flooringSolution:-Flooring cost in 1 squre meter = $40
Flooring cost in 13.5 square meters = $(40 × 13.5) = $540
Answer:-He pays $540 to buy flooring for his room.

The volume of the cylinder is 225(pi) cm³. What is the height of
the cylinder?
(A) 6.25 cm
(B) 25 cm
(C) 37.5 cm
(D) 75 cm
Answer:
it's 25 cm
Step-by-step explanation:
Volume = 225π
or πr²h= 225π
or r²h= 225
or h= 225/r²
here diameter d = 6cm so radius r=d/2 = 3cm
or h= 225/3²
hence h= 25cm
15. Ethan planted sunflowers in different types of soil and measured their growth each week.
Plant 1 started at a height of 10 inches and grew 10 inches per week. Plant 2 started at a
height of 18 inches and grew 8 inches per week. Ethan wants to predict the number of weeks
it will take for the plants to reach the same height.
Ethan concludes that the plants will reach the same height after 50 weeks. Is Ethan correct?
Explain why or why not.
Answer:
He is not correct
Step-by-step explanation:
10 x 50 = 500
500 + 10 = 510
510 represents plant 1 height after 50 weeks
8 x 50 = 400
400 + 18 = 418
418 represents plant 2 after 50 weeks
they're not the same height
Answer: No he is not correct
Step-by-step explanation:
plant 1 will be taller than plant 2 at 50 weeks
do 50 times 10 = 500in
do 50 times 8 = 400in

me Binomial
Leading Coefficient 5
Degree - 7
Number of terms=2
Name - Binomial
Leading Coefficient -5
Degree 7
Number of terms 2
Name Binomial
Leading Coefficient 5
Answer:
degree of the polynomial = 7
Number of terms = 2
Name = binomial
leading coefficient = 5
Step-by-step explanation:
The polynomial is x³y² - 5x³yz³
The degree of a polynomial is the highest exponent of any of its variables.
But in this case where we have two variable together, we sum up their exponents and the Hughes one will be the degree of the polynomial.
Thus;
x³y² has a degree of 3 + 2 = 5
5x³yz³ has a degree of 3 + 1 + 3 = 7
Thus,7 is the highest and the degree of the polynomial is 7.
There are two terms which are x³y² and 5x³yz³
Since it has two terms, it is a binomial.
To get the coefficient, I will rearrange in descending order of degree;
-5x³yz³ + x³y²
Thus, leading coefficient = 5

Karl is making a pot of chili. The recipe calls for StartFraction 3 Over 8 EndFraction cup of chili powder, but Karl only wants to use half as much so it won’t be so spicy. How much chili powder should Karl use?
Given:
The recipe calls for [tex]\dfrac{3}{8}[/tex] cup of chili powder.
Karl only wants to use half as much so it won’t be so spicy.
To find:
How much chili powder should Karl use?
Solution:
We have,
Chill power for recipe = [tex]\dfrac{3}{8}[/tex] cup
Chill power used by Karl is half of chill power for recipe.
[tex]\text{Chill power used by Karl}=\dfrac{1}{2}\times \dfrac{3}{8}[/tex] cup[tex]\text{Chill power used by Karl}=\dfrac{3}{16}[/tex] cup
Therefore, [tex]\dfrac{3}{16}[/tex] cup of chili powder should Karl use.

A box contains 3 pens, 2 markers, and 1 highlighter. Tara selects one item at random and does not return it to the box. She then selects a second item at random. What is the probability that Tara selects 1 pen and then 1 marker?
Answer:
1/5
Step-by-step explanation:
There are a total of 6 items in the beginning. In the first selection, there is a 3/6 chance that she selects a pen. Since she does not return it to the box, there are 5 items left. The possibility to select a marker is 2/5. Simply multiply the two fractions. You will get 1/5.

Step-by-step explanation:
You are multiplying x² - 4x + 4 and 6x + 3.
This is set up like:
6x + 3(x² - 4x + 4)
To solve this, we want to multiply each term that is outside of the parentheses with each term that is inside of the parentheses.
Let's start with 6x.
6x • x² = 6x³
6x • -4x = -24x²
6x • 4 = 24x
These numbers will be in the first blank row.
Now, let's move onto 3.
3 • x² = 3x²
3 • -4x = -12x
3 • 4 = 12
These numbers will be in the second blank row.
Now let's write all these numbers together.
6x³ - 24x² + 24x + 3x² - 12x + 12
Combine like terms, pay attention to the exponent.
6x³ - 21x² + 12x + 12
Refer to the completed table below.

So we know they had got $22,553 which is 90% more than last year. With this information we know:
190% = $22,553
1% = $22,553/190
1% = $118.70
100% = $11870
So overall it would be $11870 which they had got last year
