Step-by-step explanation:
Let the width be w centimeters.
Then the length = w + 7.
The area A is found from the length multiplied by the width.
330 = w(w + 7) = w^2 + 7w.
Now we can rearrange this equation to form a quadratic, as follows:
The factorization of the quadratic is:
(w + 22)(w - 15) = 0
Therefore we find that:
width = 15 centimeters
length = 22 centimeters
Answer:
8
Step-by-step explanation:
You are given the hypotenuse and one leg of a right triangle, and are being asked to find the other leg. The Pythagorean theorem applies.
TW² + TY² = WY²
TW² = 17² - 15² = 64
TW = √64
TW = 8
Answer:
2 feet per year
Step-by-step explanation:
I think you meant 38 1/2
and 5 1/2
but if you didn't then its
2.1484375
because
4912-3812=1100
1100÷512= 2.1484375
