Answer:the product of the length and the width of the rectangle could be expressed as
(x^2 - 3y)(x^2 + 3y)
Step-by-step explanation:
If the area of a rectangle is expressed as x^4 - 9y^2, we would determine the dimensions by simplifying the given expression. The simplified expression becomes
(x^2 - 3y)(x^2 + 3y)
Let us check by multiplying each term in one parenthesis by each term in the other parenthesis to get the given expression. It becomes
(x^2 - 3y)(x^2 + 3y) = x^4 + 3x^2y - 3x^2y - 9y^2 = x^4 - 9y^2
Answer:
2 1/4
Step-by-step explanation:
It is asking you to find how many pounds she has all together. First I would add all the 1/4, there are 5 1/4 Xs so that equals 1 1/4. Then i would find how many 1/2 Xs there are, here there are two, this is very good because if you have two halves it makes one whole, so it equals 1. Last you add them both together, so 1 1/4 + 1, this equals 2 1/4.
