55.46 so estimating it would just leave it at 55
Perimeter of quadrilateral ANCM = AN+NC+CM+MA
CM=AM = x in
Therefore, AN=NC = x in
In other words, all sides of the new quadrilateral are equal.
Perimeter (P) = 4x in
Now, Cos 45 = (x-6)/x =>0.7041 = (x-6)/x => 0.7041x=x-6 =>x= 6/(1-0.70741)
x= 20.5 in
Therefore, P=4*20.5 = 82 in
Answer:
a) 7x^2 + 5x
Step-by-step explanation:
(9x^2 + 8x) – (2x^2 + 3x)
Distribute the minus sign
(9x^2 + 8x) – 2x^2 - 3x
Line them up vertically
(9x^2 + 8x)
– 2x^2 - 3x
-------------------
7x^2 +5x
