You must halve the linear coefficient and then square it. In this case:
(2/2)^2=1 so you must add 1 to both sides of the equation...
x^2+2x+1=14 now the left side is a perfect square...
(x+1)^2=14
Answer:
The bottom is 11
The median is 12
Step-by-step explanation:
The median is the average of the top and bottom
(13+ 2x-3) /2 = 4x-16
Combine like terms
(10+2x)/2 = 4x-16
Divide by 2
5+x = 4x-16
Subtract x from each side
5+x-x = 4x-16-x
5 = 3x-16
Add 16 to each side
5+16 = 3x-16+16
21 = 3x
Divide by 3
21/3 = 3x/3
7 =x
The bottom is 2x-3 = 2*7-3 = 14-3 = 11
The median is 4x-16 = 4*7-16 = 28 -16 = 12

Answer:
1020?
Step-by-step explanation:
im not sure completely but the formula for volume is length x width x height
When you multiply terms with like bases you add the exponents together. The base stays the same. When you divide terms with like bases you subtract the exponent of the denominator from the exponent of the numerator. This is called getting the power of a power.
