Answer:
4x + 8
-45 - 5x
7x - 21
Step-by-step explanation:
For the first one
4(x + 2)
for distributive property you multiply the number or symbol next to the outside of the parenthesis, by everything inside the parenthesis.
4(x+2)
4*x = 4x
4*2 = 8
So, this is 4x + 8
-5(9+x)
-5*9= -45
-5*x=-5x
So, this is -45 - 5x
7(x-3)
7*x= 7x
7*-3= -21
This will be 7x - 21
Hope this helps!!
