F=60, s=60/2=30
(60-x)/(30-x)=4
60-x=120-4x
60+3x=120
3x=60
x=20
s=30-x
s=30-20
s=10
So the boy was 10 years old when his father was four times his age.
Answer: 420
<u>Step-by-step explanation:</u>
7 appetizers and 10 entrees and 6 desserts
7 x 10 x 6 = 420
The difference quotient and simplification will be = [4 -h-2x]
The given equation is as follows: f(x)= 4x - x²
For finding the quotient and further simplification we must follow the following steps:
[f(x + h) - f(x)] / h = [4(x + h) - (x + h)² - 4x + x²]/ h
<h3>What is simplification of algebraic operations?</h3>
Getting the functions in their lowest terms is known as simplification.
Brackets will get open and solved further;
[f(x + h) - f(x)] / h = [4(x + h) - (x + h)² - 4x + x²]/ h
[f(x + h) - f(x)] / h = [4h - h² - 2x]/ h
Finally dividing the whole equation with h;
= [4 - h - 2x]

If it has no stretch factor, then there will be no coefficient. Meaning this is a lot easier. So, we equation is
(x+6)^2 + 5
