Answer:
3w+7
c^2 + 4c - 3
Step-by-step explanation:
8v+w+7-8v+2w
8v-8v +w+2w +7
0+3w+7
3w+7
4c^2+6c-3c^2-2c-3
4c^2-3c^2 + 6c-2c -3
c^2+4c-3
Yes, every right triangle has two complementary angles.
This is because you know that the interior angles of a triangle have to add up to 180 degrees.
A right angle is 90 degrees, so the remaining two angles have to add up to (180-90) degrees, or 90 degrees.
Two angles whose sum is 90 degrees are complementary.

Answer:
n<-9
p (put the symbol already there here) -7
Step-by-step explanation:
Hope this helps!!
From multiplying the binomial expression
(n+3)(n-9)
It would be n^2 - 9n + 3n - 27 or simplified
n^2 -6n - 27.
