Answer:
B
Step-by-step explanation:
Try it -3 squared is 9 -4 squared is 16 , 9+16 = 25 so 
Isn't it just 6.8? Pretty sure that is the answer
X+96+5x=180
6x=84
X=14 which is B.
Check: 14+96+5(14)=110+70=180
Answer:
x^2-2x-13
Step-by-step explanation:
f(x) = 2x-5
g(x) = x^2 -4x-8
f(x) +g(x) = 2x-5 + x^2 -4x-8
Combine like terms
= x^2+2x-4x-5-8
=x^2-2x-13
Answer:
-5x-12
Step-by-step explanation:
Given f(x) = -5x+3, to get f(x+3), we are going to replace x in f(x) with x+3 as shown;
f(x) = -5x+3
f(x+3) = -5(x+3)+3
f(x+3) = -5x-15+3
f(x+3) = -5x-12
Hence the function f(x+3) is -5x-12
