AP and PB should add to AB
(2x-9)+(1.5x+6)=32
2x-9+1.5x+6=32
3.5x-3=32
3.5x=35
x=10
Plug this value of x in
1.5(10)+6
15+6
21
Final answer: 21
Answer:
B. 7 inches
Step-by-step explanation:
The surface area of a cube is denoted by: A = 6s², where s is the side length.
Here, we know that A = 294 in², so plug this into the equation to solve for s:
A = 6s²
294 = 6s²
s² = 49
s = √49 = 7
The answer is thus B, 7 inches.
Answer:
2 sqrt(2x-1)
Step-by-step explanation:
f(x) = sqrt(x+7)
g(x) = 8x-11
f(g(x))=
Place g(x) in for x in the function f(x)
f(g(x)) = sqrt( 8x-11 +7)
= sqrt( 8x -4)
Factor out 4
= sqrt( 4(2x-1)
= 2 sqrt(2x-1)
