This is a stupid question. The teacher who asked this needs to go back to school.
A = x⁴ - 9y²
That's going to be a number. As long as it's positive we can choose any length for our rectangle L and we can compute the width by W=A/L. So the correct answer is the dimensions are L by (x⁴ - 9y²)/L.
They don't want the correct answer. They want you to factor this expression. We'll do it, but don't believe for a second this factoring somehow constrains the possible dimensions of some rectangle.
We use the difference of two squares, a²-b² = (a+b)(a-b)
A = x⁴ - 9y² = (x²)² - (3y)² = (x²+3y)(x²-3y)
Answer: x²+3y by x²-3y

(Not only one answer)
Step-by-step explanation:
Estimate means to round in a way.
I would do this by making the equation to ...
320 x 20
or
320 x 25
or
320 x 30
or
325 x 25
etc.
You need 10 logs for 1 brick. To get 10 bricks you need 100 logs. You are collecting stones and 1 stone gets you 4 logs. That means to get 100 logs you’ll need 25 stones. That indirectly means that 25 stones gets you 10 bricks.
Answer:
See below
Step-by-step explanation:
sf = s0 + v0 t + 1/2 at^2
1 + (-3)t + 1/2 (.2t) t^2 ( weird acceleration value)
s = 1 -3t + .1 t^3 You will need a 't' value to determine the position
