Simplify by using the distributive property 5 ( 2x - 5 )
drek231 [11]
Hello!

The problem has asked that we simplify the given expression using the Distributive Property. The Distributive Property states the following:

a(b + c) = ab + ac
a(b – c) = ab – ac

In this case, we’ll use the second of the two formulas listed above. Let’s begin by inserting any known values given in the original problem:

a(b – c) = ab – ac
5(2x – 5) = 5(2x) – 5(5)

Now simplify the right side of the equation:

5(2x) – 5(5) = 10x – 25

We have now proven that 5(2x – 5) is equal to 10x – 25. Therefore, the correct answer is C.

I hope this helps!

Pls help!! come rack up some points!! need a lot of help today!
podryga [215]

Answer:

166

Step-by-step explanation:

SA = 2lw** + 2lh +2hw

** It's 2 x l x w, not 21 x w (it looks like a 1, I know smhh)

l = 4

w = 7

h = 5

2*4*7 + 2*4*5 + 2*5*7 = 56 + 40 + 70

56 + 40 + 70 = 56 + 110

56 + 110 = 166
