The inverse of subtraction is addition
This is the expression simplified:
Answer:
-5 =x
Step-by-step explanation:
3^(x-1) = 9^(x+2)
Replace 9 with 3^2
3^(x-1) = 3^2^(x+2)
We know that a power to a power means the powers are multiplied
a^b^c = a^(b*c)
3^(x-1) = 3^(2x+2)
When the bases are the same, the powers have to be the same
x-1 = 2x+4
Subtract x from each side
x-x-1 =2x-x+4
-1 =x+4
Subtract 4 from each side
-1-4 =x+4-4
-1-4 = x
-5 =x
Answer:
The volume would be 31 cubic feet.
Step-by-step explanation:
To find this, use the formula for the area of a right pyramid.
A = 1/3bh
A = 1/3(8)(12)
A = 1/3(96)
A = 32
