Answer:
n(n + 6)
Step-by-step explanation:
n² + 6n = n(n + 6)
We have that
the volume of a right square pyramid ---------- > (1/3)b²h
Let
V1------------ > initial volume
V1=(1/3)b²h
<span>if its height is multiplied by 8
</span>
V2=(1/3)b²(8h)-------------- > V2=V1*8
therefore
the answer is the option D
the factor is is 8
A.
Divide the numbers
1 + 4x 2/2 • x =5x
1 + 4x + 1x =5x
Multiply by 1
1 + 4x + 1x=5x
Combine like terms
1 + 4x + x =5x
1 + 5x =5x
Subtract 1 from both sides of the equation
5x + 1 = 5x
5x + 1 - 1 =5x -1
Simplify
Subtract the numbers
5x = 5x -1
Subtract 5x from both sides of the equation
5x = 5x -1
5x - 5x = 5x -1 -5x
Simplify
0= -1
Result
0= -1
idk the ans in letter B
