F(0)= 2* 0 +3
=0+3
f(0)=3
So when X is 0, the area of the pool is 1200. That makes A and C impossible... then you can plug in numbers...say the boardwalk is 1 ft wide, add 2 to each dimension and plug in 1 for X. (You're adding 2 because there is a tile on either side of each dimension, including corners).
32x42=1344=4+140+1200
Therefore the answer is B.
The answer is 2x-10.
(x-5)2
=(x+-5)(2)
=(x)(2)+(-5)(2)
=2x-10
Answer:
h=7.65
Step-by-step explanation:
h=k√p
k=h/√p
k=5.4/√1.44
k=4.5
h=4.5√p
when p=2.89
h=4.5√2.89
h=7.65
