Using distributive property you use FOIL method so 2x • 2x= 4x^2 2x•-1= -2x 7•2x= 14x 7•-1= -7 put that all together 4x^2 -2x +14 x -7 combine like terms which is -2x+14x= 12x final answer: 4x^2 + 12x - 7
The answer is C) $30.00.
First, find out how much 1lb costs. 1lb would cost 1/4 of 4lb.
$10×1/4=$2.50/1lb.
So 12 pounds would be 12x the cost of 1lb.
$2.50×12 pounds=$30/12lb.
