Answer:
Distributive property
Step-by-step explanation:
The distributive property tells you ...
a(b+c) = ab +ac
Here, you have a=4, c=2, so ...
4(b+2) = 4·b + 4·2 = 4b +8
Below
Which is distributive property!

thanks!
5×4= 20
20×10= 200
200×0.15 = 30
B. $30
x =
Given
y = 4x - 10 ( add 10 to both sides )
y + 10 = 4x ( divide both sides by 4 )
= x
