Question 11 What is the best first step to solve the following quadratic equation?
16x^2 + 38 = -40x
A
Add 40x to both sides.
B
Factor the right side.
c
Take the square root of both sides.
D
Multiply 16 by 38 and list the factors.

expression #3 is not equivalent. the others are.

$4034.40

the perimeter of the field is the sum of the lengths of the four sides:

47 yd + 158 yd + 47 yd + 158 yd = 410 yd

the cost of 3 ft (1 yd) of fence is 3×$3.28 = $9.84.

so the cost of jake's wood perimeter fance is

(410 yd) × ($9.84 /yd) = $4034.40
