The angle of NPR is 130°
First, set up an equation to find x.

Then, solve the equation for x.

Then, substitute 25 in for x in 2x
50
Finally, subtract 50 from 180 to find the angle of NPR
130°
If it is 20% off, then ur actually paying 80%
so an equivalent expression would be 0.80p
5 times 5 times 5 times 5 is 20
So just count by 5
Hope this help
6x² + 48x + 96
6(x² + 8x + 16)
6(x + 4)(x + 4) is your polynomial fully factored so I'm guessing the binomial you're looking for is (x + 4).
