Math Problem Statement

Which expression is equivalent to -9(-2a - 5) - 8?

Solution

Let us analyze and solve the problem step by step.

The given expression is:

9(2a5)8-9(-2a - 5) - 8

Step 1: Distribute the 9-9

We distribute 9-9 to each term inside the parentheses:

9(2a5)=(9)(2a)+(9)(5)-9(-2a - 5) = (-9)(-2a) + (-9)(-5)

=18a+45= 18a + 45

Step 2: Add the remaining 8-8

Now substitute back into the expression:

18a+45818a + 45 - 8

Simplify the constants:

18a+3718a + 37

Step 3: Match with the given options

The simplified expression 18a+3718a + 37 is equivalent to none of the provided options. The closest might have been checked against its format. Would you want me to conficalulatate the collatch over nit-continue plots
