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!
1. We are given:

The only a which squared gives you 64 is 8. The perimeter of an 8 by 8 square will be 32. Half of that is 16. Now, let's see what we can do. We can set up:

Obviously, each side length has to be 4. So, the area of this square will be
16 units².
2. Let n equal her son's age. So, her age right now will be (S = her age):

1 year ago it was:

We have 2 equations, let's substitute. We can rewrite this as:

Solve for n:


We know the value of n, which is her son's age. So, her son is
1/15 of a year old or about 24 days old.
Answer:
1/2
Step-by-step explanation:
4/8 are red. If you simplify that you get 1/2.
Answer:
144
Step-by-step explanation:
exponents first: 
then division: 100/5 = 20
now we have: 20 x 4 + 64
then multiply: 20 x 4 = 80
then add: 80 + 64 = 144
2x^3 - 18x^2 + 40x
2x(x^2 - 9x + 20)
2x(x - 5)(x - 4)
Answer is c) x - 5
