The absolute value of 9 is 9. The absolute value of a number cannot be negative.
(4a+6b)×(a-b)
=4a(a-b)+6b(a-b)
=4a^2-4ab+6ab-6b^2
=4a^2+2ab-6b^2
15 pieces will there be.
<h3> How many pieces will there be?</h3>
.5 is the same as 1/2, while 7.5 is the same as 7 1/2. To determine how many strips may be cut, use the following expression:
.5x = 7.5
This is due to the fact that the ribbon length that has to be cut is .5 feet, and we are attempting to determine how many pieces of that length might be cut from a roll of ribbon that is 7.5 feet long.
Divide both sides by 2.5 to separate the variable, and that's all there is to it.
7.5/.5 is 15.
x = 15.
Eli is able to slice a ribbon into three pieces that are each .5 feet long.
The complete question is: The red strips that are 1/2 feet long. The roll of ribbon is 7 1/2 feet long. Which expression could be one of the steps in determining how many strips can be cut?

First things first when multiplying and dividing positive and negative numbers if the two signs are the same it's positive, and if both signs are different it's negative.
you simply just multiply and divide the same as you would normally you just have to pay attention now if the answer is positive or negative.
