Answer: 12

Step-by-step explanation:

This means you should write out the equation and replace -3 with x

Given the equation −2x(x+5)

-2 (-3) (x +5)........open the first bracket

6 ( -3 + 5) ......then open the second bracket

6 ( 2) = 6 x 2

= 12

I hope this is clear, please mark as brainliest answer.
