Use ac method
multiply 12 and -56
-672
now find what 2 factors of -672 add to -89
answer is -96 and 7
expand the middle term like that
12x²-96x+7x-56
group
(12x²-96x)+(7x-56)
factor
12x(x-8)+7(x-8)
undistribute the (x-8)
(x-8)(12x+7) is answer

Hello, I Am BrotherEye
Answer: 28 cubes
Step-by-step explanation:
The answer to part a should by 1/2 inch because the cube must fit within the smallest dimension of the rectangular prism. If the cube were larger, it would not fit inside the 1/2 inch length.
1. Four 1/2 inch cubes would add up to the 2 inch side of the rectangular prism.
2 ÷ 1/2 = 4
2. Seven 1/2 inch cubes would add up to the 7/2 inch side of the rectangular prism.
7/2 ÷ 1/2 = 7
This means that four rows of seven 1/2 inch cubes can fit within the rectangular prism.
3. Multiply.
7 · 4 = 28 cubes
