The easiest way to do this is for you to subtract all the sides from the total perimeter since the perimeter is all of the sides added and your remainder is your answer
Step-by-step explanation:x squared is one x.you then add the X's to get 2x.then you subtract the five on the other side to get 2x=6.after you get that you divide both sides by 2 to get x=3
Let us first describe how partial product and regrouping are alike:
Partial Products and Regrouping are alike because both methods are multiplied by one number and if the product of the number has 2 digits it can be carried.
Now let us discuss how they are different:
Partial Products and Regrouping are different because Partial Products are doing multiplication step by step and regrouping is regular multiplication.
