Answer:
x^4+x³+7x²-6x+1
Step-by-step explanation:
(x²+2x+8)(x²-x+1)
distribute
x²(x²-x+1)
x^4-x³+x²
2x(x²-x+1)
2x³-2x²+2x
8(x²-x+1)
8x²-8x+1
x^4-x³+x²+2x³-2x²+2x+8x²-8x+1
combine like terms
x^4+x³+7x²-6x+1
the diagonal of a rectangle is square root of (w^2 +l^2)
so square root of (14^2 +10^2) = 17.2 inches
since 20" is longer than 17.2 it can't be a rectangle
Answer:
n= 12 m=5
Step-by-step explanation:
Because it is a parallelogram, the parallel sides are equal in length. So n = side length 12. n = 12
For the other one, m + 1 = 6
Be careful to solve for m, not m+1.
m=6-1
m=5
