Question

If ab=x+5 and BV=2x-11 find the measure of AB

Answer 1

First solve for B in VB = 2x-11

BV = 2x - 11
BV / V = 2x - 11 / V
B = 2x - 11 / V

Now solve for A in AB = x + 5
AB = x + 5
AB / B = x + 5 / B
A = x + 5 / B

Now times A and B

`(x + 5)/(B) * (2x - 11)/(V)`
Now multiply

`(x + 5)/(B) * (2x - 11)/(V)`
(x + 5)(2x - 11)

`2x^2 - 11x + 10x -55`

`2x^2 - 1x -55`
V * B = VB
So our answer is below

`(2x^2 - 1x -55)/(VB)`
