Write an expression that includes the numbers 2,4,and 5, has a Value of 50, and includes one set of parentheses.

The required expression that includes the numbers 2,4, and 5, has a value of 50 is  5(4 + 2) + 5(4)

Expressions are mathematical statements having two or more variables and connected by mathematical signs. The mathematical signs can be +, - and *

According to the question, we are to form an expression with 2, 4, and 5 that will give 50.

Connecting the integers using the given signs, we will have:

5(4 + 2) + 5(4)

Checking:

Expand the expression using distributive law:

= 5(4) + 5(2) + 5(4)

= 20 + 10 + 20

= 30 + 20

= 50

This that one of the arrangement in parenthesis is 5(4 + 2) + 5(4)

Step-by-step explanation:

If you simplify the 1st equation,

5x + 9 - 2x = 12

Add like terms

3x + 9 = 12  

Subtract the 9 from both sides

3x = 3

It gives you the same equation as the other one
