6-z
Z-6 would be wrong because the question said start with 6
Answer:
7.2*10^3.
7,200 in scientific notation, is 7.2*10^3
Answer:
The table shows values for Variable A and Variable B.
Variable A 1 5 2 7 8 1 3 7 6 6 2 9 7 5 2
Variable B 18 22 19 7 24 16 17 20 20 23 17 25 21 18 15
Use the data from the table to create a scatter plot.
Step-by-step explanation:
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
So you can play? I guess...
