Translating into a mathematical equation:
n + n^2 = 72
Rewriting, n^2 + n - 72 = 0
Factoring, (n+9)(n-8) = 0
Solving for n: n = -9 or n = 8
You must check both answers before accepting one, the other or both.
Example: suppose we check out n = 8. Then 8 + 8^2 = 72 is true, and n = 8 is a solution. Is n = -9 a solution? Try it.
1 acre = 43560 square feet
43560 = 484 * X
X=43560/484 = 90
the width = 90 feet
Answer:
The conversion factor is upside down. The tsp will not cancel
Step-by-step explanation:
The conversion factor is upside down. The tsp will not cancel
15 tsp * 1 tbsp
--------- = 15/3 tbsp = 5 tbsp
3 tsp
Step-by-step explanation:
well, what would you think ?
since the line NO bisects the angle at N (MNO), it bisects also the line MO.
"bisecting" simply means "cutting in half". that means both resulting parts are equally large.
therefore, MO = PO = 8
