How could writing a problem using an exponent be easier to understand than repeated multiplication?
Answer:
One reason, is because it clearer and easier to read.
Seeing two numbers (3^5) can let you know, in this example, 3x3x3x3x3 is harder to understand than 3^5.
3 is the number being multiplied, and 5 tells you how many times.

36 − 9m^2 factorized
Answer:
Step-by-step explanation:
Note that the expression is the difference of squares.
36 - 9m² = 6² - (3m)²
6² - (3m)² = (6 + 3m) (6 - 3m)
Answer:
9(2+m)(2-m)

What is the length of the missing leg ?
Answer:
A=4
Step-by-step explanation:
you use the Pythagorean Theorem,
a triangle having a Leg b length of 3 and a Hypotenuse c length of 5 would have a Leg a length of 4.
Here is how I solved for Leg a using the Pythagorean Theorem.
Leg a = sqrt[ (Hypotenuse c)2 - (Leg b)2 ]
Leg a = sqrt[ (5)2 - (3)2 ]
Leg a = sqrt[ 25 - 9 ]
Leg a = sqrt[ 16 ]
Leg a = 4

what is the distance between (-1, 2) and (5, -2)on a graph put into a decimal form.
Given:
The two points are (-1,2) and (5,-2).
To find:
The distance between the given points.
Solution:
Distance formula:
[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Using the distance formula, the distance between the given points is
[tex]d=\sqrt{(5-(-1))^2+(-2-2)^2}[/tex]
[tex]d=\sqrt{(5+1)^2+(-4)^2}[/tex]
[tex]d=\sqrt{(6)^2+16}[/tex]
[tex]d=\sqrt{36+16}[/tex]
On further simplification, we get
[tex]d=\sqrt{52}[/tex]
[tex]d=7.2111[/tex]
[tex]d\approx 7.21[/tex]
Therefore, the the distance between the given points is about 7.21 units.
In 12 years, Janice will be 8 times as old as she was 2 years ago. How old is Janice
now?
Janice is currently 4.
In 12 years, Janice will be 16, and 2 years ago she was 2. That being said, 16 is eight times more than 2, thus meaning she is currently 4 years old.

Find the area of the composite figure.
21 ft
12 ft
9 ft
9 ft
6 ft
6 ft
Answer:
738 square ft
Step-by-step explanation:
Area of the composite figure
= 21*(12 + 9 + 6) + 9*(9 + 6) + 6*6
= 21*27 + 9*15 + 6*6
= 567 + 135 + 36
= 738 square ft
someone please answerrrrrr
3(x-4) = 2(-2x + 1)
this is confusing me
Answer:
x = 2
Step-by-step explanation:
Distribute
3 (−4) = 2 (−2+1)
3 − 12 = 2 (-2x +1)
Distrubute again
3x - 12 = -4x + 2
Add twelve to both sides of the equation
Simpfly
3x = -4x + 14
Add 4x to both sides of the equation
simpfly
7x = 14
Divide both sides of the equation by the same term
Simpfly
x = 2
Rebecca is climbing up a 500-foot cliff. By 1:00 P.M., she has
climbed 125 feet up the cliff. By 4:00 P.M., she has reached
an altitude of 290 feet. Find the average rate of change in
Rebecca's altitude during the three hours. Give the rate in feet
per bour.
Answer:
Step-by-step explanation:
(290 ft - 125 ft)/(3 hours) = (165 ft)/(3 hours) = 55 ft/hour

Converting from vertex form to standard form
[tex]y = \frac{1}{2} (x - 2) {}^{2} - 4[/tex]
Answer:
[tex]\displaystyle f(x)=\frac{1}{2}x^2-2x-2[/tex]
Step-by-step explanation:
To convert from vertex form to standard form, we can simply expand.
So, we have:
[tex]\displaystyle f(x)=\frac{1}{2}(x-2)^2-4[/tex]
Expand the square:
[tex]\displaystyle f(x)=\frac{1}{2}(x^2-4x+4)-4[/tex]
Distribute:
[tex]\displaystyle f(x)=\frac{1}{2}x^2-2x+2-4[/tex]
Simplify:
[tex]\displaystyle f(x)=\frac{1}{2}x^2-2x-2[/tex]
One number is five less than a second number. Five times the first is 8 more than 6 times the second. Find the numbers.
The value of the first number is ____
Answer:
-38
Step-by-step explanation:
Let's say that x= 1st number and y=2nd number.
In order to find the first number, you have to find out the 2nd number which it says, "5 less than a second number", it would be y-5. then it says the "5 times the first is 8 more than 6 times the second". then there should be an equal sign because there is the word "is". The expression would be: 5(y-5)=6y+8. then solve the y. which is -33, then plug in the y to the y-5 and there you go!

Step-by-step explanation:
The point (2.5, 1) is also on the line. What is the vertical change between (2.5, 1) and (5, 2)? What is the horizontal change?
Answer:
In a general point (x, y) the horizontal component is the x-component, and the vertical component is the y-component.
then if we have the points (a, b) and (c, d)
The vertical distance or change between these points will be the difference between the y-components, and the horizontal distance or change is the difference between the x-components.
Then the vertical change between the points (2.5 , 1) and (5, 2) is:
2 - 1 = 1 unit.
The horizontal change between the points (2.5, 1) and (5, 2) is:
5 - 2.5 = 2.5 units.
Which expression is equivalent to
3x +10- x + 12?
A. 26x
B. 4x + 22
C.2x + 22
D. 24x
Answer:
2x + 22
Step-by-step explanation:
3x - (1)x = 2x
10 + 12 = 22
therefore 2x + 22 is your answer
Answer:
C
Step-by-step explanation:
subtract : 3x - x = 2x
Add : 10 + 12 = 22
Answer: 2x + 22
