If the given are h =2x+9, l = x+2, w = 3x, then the answer is 6x^3+39x^2+54x
V = lwh
= (2x+9)(x+2)(3x)
= (2x^2 + 4x + 9x + 18)(3x)
= 6x^3 + 12x^2 + 27x^2 + 54x
= 6x^3 + 39x^2 + 54x
Answer:
-2
Step-by-step explanation:
Subtract 10 on both sides:
6x +10= -2
-10 -10
6x = -12
Divide by 6 on both sides:
6x = -12
/6 /6
x = -2
Answer:
There was a 15 among the 7 numbers. That is the number you removed.
Step-by-step explanation:
x/7 = 9 (1)
(x - y)/6 = 8 (2)
Multiply 1 by 7
x/7 * 7 = 9*7
x = 63
Put 63 for x into equation 2
(63 - y)/6 = 8 Multiply by 6
6*(63-y)/6 =8*6
63 - y = 48 Add y to both sides
63-y+y = 48+y
63 = 48 + y Subtract 48 from both sides
63-48=48-48+y
y = 15
