I could be wrong, but I'm pretty sure here the answer would be 10x^2 + 17x +3 would be the area since you have to multiply length and width. since these are expressions with no answers and no other numbers, we can't find x.
Answer:
<h2>z = 15</h2>
Step-by-step explanation:

<u>Cross multiply </u>
That's

<u>Send 15 to the right side of the equation</u>

Divide both sides by 15

We have the final answer as
<h3>z = 15</h3>
Hope this helps you
The slope would be -65 and this would indicate the the car is going 65 miles per hour, as it is being subtracted from the distance.
Your answer would be C
Answer:
62% and 161.29%
Step-by-step explanation:
Given that the percentage of adult height attained by girls who are x years old can be modeled by
, where
x represents the girl's age (from 5 to 15) and
f(x) represents the percentage of her adult height
A) When age =5, we have x=5

So height when age is 5 is 62 %
B) The approximate of her adult height is

(10x + 4) + (5x-4) ≈ 180
solve for x and you get x≈12
plug 12 in to 5x-4 and you get 56
