Write and evaluate two equivalent numerical expressions that show Distributive Property of Multiplication
Ainat [17]

Answer:

2(x+5) = 2x+10

Step-by-step explanation:

I'm assuming you can use any possible combination of two equivalent numerical expressions for your question.

2(x+5) = 2x+10

2 times x is 2x. 2 times 5 is 10. So, you get 2x+10

Simplify. <br><br> −3x3(−2x2+4x−3)
stepladder [879]

Answer:

-3x^3(-2x^2+4x-3) simplifies to 6x^5-12x^4+9x^3

Step-by-step explanation:

Given expression -3x^3(-2x^2+4x-3)

We have to simplify the above expression,

Consider the given expression -3x^3(-2x^2+4x-3)

Multiply each term in brackets by -3x^3, we get,

-3x^3(-2x^2+4x-3)=-3x^3(-2x^2)-3x^3(4x)[-3x^3(-3)

Solving further,  using x^n\cdot x^m=x^{n+m} we get,

-3x^3(-2x^2)-3x^3(4x)[-3x^3(-3)=6x^5-12x^4+9x^3

Thus, -3x^3(-2x^2+4x-3) simplifies to 6x^5-12x^4+9x^3

Took Gage 1 of a gallon of paint to create a mural of his favorite team the Grizzlies. He was asked to replicate his mural for 8
Charra [1.4K]

Answer: He will need 8 gallons of paint for the other murals.

Step-by-step explanation:

Given: 1 gallon of paint was required to create 1 mural.

Since replicates have the same dimensions, i.e same total surface area.

So, if 8 replication need to be made, the quantity of the paint required for this will be

8  x (Quantity required for 1 mural)

= 8 x 1

= 8 gallons

Hence, he will need 8 gallons of paint for the other murals.
