First you divide L+W by 2 and you would get A/2=L+W then you would subtract L and get A/2 -L=W
All you do is multiply 15 and 6 you get 90. then divide 90 by 9 and you get 10.
(5x³ + 4x²) - (6x² - 2x - 9)
-1(6x²) -1(-2x) -1(-9) = -6x² + 2x + 9
5x³ + 4x² - 6x² + 2x + 9
5x³ - 2x² + 2x + 9 Choice D.
The length of the base is 32.6
3.3 + 3.3 = 6.6
Subtract 6.6 from 71.8 : 65.2
Divide that by 2 : 32.6
