Answer:
What is the question?
Step-by-step explanation:
PEMDAS: distribute the negative to (-2-5x) so it becomes (2+5x)+(-2)=18
Add 2 to both sides: 2+5x=20
Subtract 2: 5x=18
Divide 5: x= 18/5
Answer: A

Answer:
2L^2 - 27L + 70 = 0.
Step-by-step explanation:
p = 2(L + W)
27 = 2L + 2W
2W = 27 - 2L
W = (27 - 2L)/2
Substitute for W in the area equation:
A = LW
35 = (27 - 2L) * L / 2
L(27 - 2L) = 70
-2L^2 + 27L - 70 = 0 Multiply through by -1:
2L^2 - 27L + 70 = 0
2/5 divided by 5 equals 0.08
