Answer:
27x-68
Step-by-step explanation:
-4(2x+3)+7(5x-8)
= -8x-12+35x-56
=27x-68
<h2>
Maximum area is 25 m²</h2>
Explanation:
Let L be the length and W be the width.
Aidan has 20 ft of fence with which to build a rectangular dog run.
Fencing = 2L + 2W = 20 ft
L + W = 10
W = 10 - L
We need to find what is the largest area that can be enclosed.
Area = Length x Width
A = LW
A = L x (10-L) = 10 L - L²
For maximum area differential is zero
So we have
dA = 0
10 - 2 L = 0
L = 5 m
W = 10 - 5 = 5 m
Area = 5 x 5 = 25 m²
Maximum area is 25 m²

take the absolute value of the coefficient (2)
then the lower bound is the negative of that (-2)
so the range is [-2,2]
