Step-by-step explanation:
2x^2 + x - 28
= 2x^2 - 8x + 7x - 28
= 2x(x-4) +7(x-4)
= (2x+7)(x-4)
2x+7 = 0 or x-4 = 0
x = -7/4 or x = 4
Answer:
That would be about 11.667
81m+27t
We need to distribute the 9 to the terms inside the parentheses:
9(9m+3t)=9(9m)+9(3t)=81m+27t
72
36 x 2 = 72
To check your answer:
72 / 2 = 36
