24am - 9an + 40bm - 15bn = 3a*(8m - 3n) + 5b*(8m - 3n) = (3a + 5b)*(8m - 3n)
No because 4m = 400cm.
The GCF is 8. 8(m + n)
mn - 4m - 5n + 20 = (mn - 5n) - (4m - 20) = n(m - 5) - 4(m - 5) = (m -5)(n - 4)
No because 4m equals 400 cm which is less than 450 cm
4m+15=8m-5 or,4m=20 or,m=5
4m
96m3
2(4m - 3)
224 m to the 3rd power
2(4m-3)
8m-7<4m+5

It appears to be a scalene triangle from the given dimensions.
7*8*4 = 224 cubic metres.
m2 + 8m - 65 = (m + 13) (m - 5)
Rectangles are really simple. The perimeter is twice the length plus twice the width (in this case 4m x 2 = 8m, 5m x 2 = 10m, and 8m + 10m = 18m). The area is simply the length times the width (in this case, 4m x 5m = 20m2).
