Use the distributive property to simplify the expression.

-7 (8x - 3) + x

A. x + 10

B. - 15x + 4

C. - 9x - 4

D. - 55x + 21

D

Step-by-step explanation:

Distributive property: a * (b+c) = a*b + b*c

-7 (8x - 3) + x = - 7*8x - 3 * (-7) + x

= - 56x + 21 + x {Bring the like terms together}

= - 56x + x + 21 {Now, add the like terms}

= - 55x + 21
