Answer:
(x + 3)(x + 7)
Step-by-step explanation:
Given
x² + 10x + 21
Consider the factors of the constant term (+ 21) which sum to give the coefficient of the x- term (+ 10)
The factors are + 3 and + 7, since
3 × 7 = 21 and 3 + 7 = 10, hence
x² + 10x + 21 = (x + 3)(x + 7)

Answer:
Option C. 
Step-by-step explanation:
we know that
If two figures are similar, then the ratio of its corresponding sides is proportional
In this problem
Using proportion
Alright, we know that the slope intercept form is y=mx+b, where x and y remain variables, m stands for the slope and b stands for the y intercept.
Because you should already have the slope from the first part (because slope is the same thing as rate of change), you should know that the slope is 60. The y-intercept should be your y value when x=0, and if you set up the equation in terms of years since Elliot has started his business, the year 2000 should be equal to x=0, so the y intercept should be equal to 750.
Now that you know the slope intercept form and what each part of it means, you can plug in what you have to get the final equation, which should be y=60x+750
Answer:
16.4 m to the nearest tenth.
Step-by-step explanation:
After the first bounce it rises to a height of 50*0.8 = 40 m.
After the next bounce it rises to 50*(0.8)^2 = 32 m
So after the 5th bounce it rises to 50(0.8)^5 = 16.4 m. (answer).
