Answer:
D) 2x² + 4x - 30
Step-by-step explanation:
Follow the FOIL method:
FOIL =
First
Outside
Inside
Last
...and is the order you multiply to solve:
(x + 5)(2x - 6) =
(x)(2x) = 2x²
(x)(-6) = -6x
(5)(2x) = 10x
(5)(-6) = -30
Combine like terms. Simplify:
2x² -6x + 10x - 30 = 2x² (-6x + 10x) - 30 = 2x² + 4x - 30
2x² + 4x - 30 is your answer.

Answer:
Step-by-step explanation:
A circle with a radius of 5 units has a circumference of 31.416 units.
Answer:
D)22.5cm
CB/BA=HG/13.5
CB=15cm,BA=9cm,HG=x and GF=13.5
15/9=x/13.5(divided by 13.5both sides)
x=22.5cm
