The answer is
-2(u+3)-5u
-2u-6-5u
-3u-6
Answer:
Step-by-step explanation:
area of base = 240 in²
volume = (area of base)× height
2880 in³ = 240 in² × height
height = 2880/240 = 12 in
Answer:
2
Step-by-step explana
(6x-y+4)*2= 12x -2y+8= (3x+9x)-(2y-8)
A + m = 54, m = a + 4 and, a + m = 54, - a + m = 4,
Combine the equations: 2m = 58
Now solve: 2m = 58, 2m/2 = 58/2, m = 29, therefore a = 24
