Our quadratic polynomial function is:
f(x) = 4x^2 + 2x + 5
our linear binomial form is:
x - a = -2
hence:
a = x + 2
and so we have:
f(x) = 4x^2 + 2x + 5
f(a) = 4(x + 2)^2 + 2<span>(x + 2)</span> + 5
= 4(x^2 + 4x + 4) + 2x + 4 + 5
f(a) = 4x^2 + 18x + 25
So, 3 workers are to 28 hours and x is to 12 hours. That can be written as
3 28
--- --
x 12
Multiply them to get 94 over 12. 84 divided by 12 is 7.

Step-by-step explanation:
Answer:
900 sq ft
Step-by-step explanation:
The area of a trapezoid is (Base 1 + Base 2) * height/2. So to plug the numbers in...
(30+60)20/2
90*20/2
1800/2
900 sq ft
