Answer:
Step-by-step explanation:
P=2l+2w
28=2l+2w
2l=2w-28
l = (2w-28)/2
l =2(w-14)/2
l = w-14
Answer:
Step-by-step explanation:
The given functions are
and
By the algebraic properties of functions:
We just have to substitute to obtain:
The first choice is correct.
Answer:
Step-by-step explanation:
H(x)=0
-2x^2 +4x+16=0
X^2 - 2x - 8 = 0
(X + 2) (x-4) = 0
X + 2 = 0 or x -4 = 0
X= -2 or x=4
Since -2 doesn’t make sense use 4
The ball will hit ground in 4 seconds
