Question

Simplify −4d(5d2−12)+7(d+5)

Answer 1

Explanation:

Let's simplify the expression:

-4d(5d^2-12)+7(d+5)

First, let's distribute the -4d to the terms inside the parentheses:

-20d^3 + 48d + 7(d+5)

Next, let's distribute the 7 to the terms inside the parentheses:

-20d^3 + 48d + 7d + 35

Combine like terms:

-20d^3 + 55d + 35

So the final simplified expression is:

-20d^3 + 55d + 35.
