Answer:

104

155

180

Step-by-step explanation:

an easy way is to solve what is in the parenthesis then multiply by the outside number

but if you need to use the distributive property:

1. 4 x (20 - -6)

(4 x 20) - (4 x -6) = 80 - -24 = 80 + 24 = 104

2. -5 x (24 - -7)

(-5 x 24) - (-5 x -7) = -120 - 35 = 155

3. 12 x (-30 + 45)

(12 x -30) + (12 x 45) = -360 + 540 = 180

Answer:

x = -7

Step-by-step explanation:

The given equation is :

-30=5(x+1)

We need to solve the equation.

Use associative property on RHS.

-30 = 5x+5

Subtract 5 from both the sides.

-30-5 = 5x+5-5

-35 = 5x

x = -7

Hence, the value of x is -7.
