Answer:
c
Step-by-step explanation:
F(x)=x^2+3x+5
f(3+h)=(3+h)^2+3(3+h)+5
f(3+h)=9+6h+h^2+9+3h+5
f(3+h)=23+9h+h^2
B. 11.0 cm, since the area of a square is x^2. 11.0 x 11.0 is 121. So that means one of the sides is 11.0
Hello!

The two angles pictured are corresponding angles, so they are congruent.
Therefore:
17x - 4 = 12 + 15x
Isolate for x by subtracting 15x from both sides:
2x - 4 = 12
Add 4 to both sides:
2x = 16
Divide both sides by 2:
x = 8.
187/3 = 62.33/1
