Jade wants to verify that the expression 5(3x – 6) is equivalent to 15x – 30. she substitutes 2 into each expression and evaluates each one. how will she know if 5(3x – 6) is equivalent to 15x – 30?

5(3x - 6) is equivalent to 15x - 30

Step-by-step explanation:

Jade wants to verify that the expression is equivalent to . She substitutes 2 into each expression and evaluates each one.

To verify the expression lets substitute in 2 for x

We do the same with equivalent expression

When we substitute 2 for x we got 0 for both expressions

So 5(3x - 6) is equivalent to 15x - 30

the dimensions are:

step-by-step explanation:

we want to find the dimensions of a rectangular box with volume of

we factor to obtain;

we rewrite the rightmost factor to obtain;

recall that:

we apply difference of two squares formula to obtain;

hence the dimensions are
