Solve the equation using the distributive property and properties of equality.

-5(a + 3) = -55

What is the value of a?

a = 8

Step-by-step explanation:

-5(a + 3) = - 55

- 5a - 15 = - 55

55 - 15 = 5a

5a = 40

a = 40 : 5

a = 8

a=8

Step-by-step explanation:

If we're using the distributive property, we should  first open parentheses by multiplying -5*a and -5*3

-5*a= -5a

-5*3= -15

Now, we have the equation: -5a-15= -55

Add fifteen to both side:

-5a= -40

a=8

i belive those are the ones that are under 90 degreese.
