Answer:
Step-by-step explanation:
24: 1, 2, 3, 4, 6, 8, 12, 24
40: 1, 2, 4, 5, 8, 10, 20, 40
So the Greatest Common Divisor [GCD] is <em>eight</em>; you factor that out, leaving the remaining result inside the brackets.

You bought 5 erasers.
You have the erasers sold for 4 dollars each and you have only 20 dollars left over to buy erasers so you divide 20 by 4 to get 5

Given
- 1(x + 7)(x - 4)
each term in the second factor is multiplied by each term in the first factor, that is
leaving the multiplier of - 1 for the time being
x(x- 4) + 7(x - 4) ← distribute both parenthesis
= x² - 4x + 7x - 28 ← collect like terms
= x² + 3x - 28
Hence
- 1(x² + 3x - 28) = - x² - 3x + 28 → D
