8x²-18xy-5y²
8x²+2xy-20xy-5y²
2x(4x+y) -5y (4x+y)
= (2x-5y) (4x+y)
Answer:
width = 540
Length = 540 * 4 - 30 = 2,130
Hope that helps! :)
<span>Hollis travels 0.05 miles per minute faster than Charmaine.
First, convert to the same units for both Hollis and Charmaine. So Hollis takes 18.5 minutes and Charmaine takes 0.5*60 = 30 minutes. Both girls travel 2.4 miles, so calculate how many miles per minute each takes
Hollis = 2.4 / 18.5 = 0.13 miles per minute.
Charmaine = 2.4 / 30 = 0.08 miles per minute.
Finally determine the difference in speed between the two girls.
0.13 - 0.08 = 0.05 miles per minute.</span>
Answer:
b. x ≤ 8
Step-by-step explanation:
x - 5 ≤ 3
x ≤ 3 + 5
x ≤ 8
Answer:
-4m + 6 = 14
Explanation:
You subtract 3m from both sides of the equal sign, meaning:
-m - 3m;
and 3m - 3m.
Both 3m cancels out, and since -m = -1m, you subtract like normal.
-1 - 3 = -4.
So then, you just rewrite the equation.
-4m + 6 (from the original) = 14 (3m is gone now because you canceled it out/subtracted it out.)
