B)(x+10).(x-6)=x²-6x+10x-60
x²+4x-60
C)(x+15).(x-4)=x²-4x+15x-60
x²+11x-60
D)(x+20).(x-3)=x²-3x+20x-60
x²+17x-60
But A,
(x+12)(x-5)=x²-5x+12x-60
x²+7x-60
A, is the correct answer..
GOOD LUCK!
Answer:
5:4
Step-by-step explanation:
There are 12 inches in one foot, so there are 24 inches in 2 feet.
Therefore, the ratio that compares 30 inches to 2 feet is the ratio that compares 30 inches to 24 inches.
This is

Simplify it:

A and B: m = 3/4
C and D: m = 1/2
E and F: m = 1/6
You have to use the formula cost over quantity
Divide 8 and $2.88
The answer is.
0.36
