Answer:

Step-by-step explanation:
we know that
The area of the polygon is equal to the area of a square plus the area of four congruent triangles
so
![A=b^2+4[\frac{1}{2}(b)(h)]](https://tex.z-dn.net/?f=A%3Db%5E2%2B4%5B%5Cfrac%7B1%7D%7B2%7D%28b%29%28h%29%5D)
where

substitute
![A=8^2+4[\frac{1}{2}(8)(4)]](https://tex.z-dn.net/?f=A%3D8%5E2%2B4%5B%5Cfrac%7B1%7D%7B2%7D%288%29%284%29%5D)

Answer:
A = 2,384.1708
Step-by-step explanation:
A = P(1 + rt)
P = 942.36
r = 12.75%
t = 12 months
A = 942.36(1 + 12.75/100(12))
A = 942.36(2.53)
A = 2,384.1708
The factors are the parts that are being multiplied together.
4 and (5+x) are the two that are being multiplied and also the expression you get when you factor the distributed expression.
So the factors of 4(5+x) are:
4 and (5+x)
Answer:not sure but i think 10 *25)/20 * 16 - 10
Step-by-step explanation: i think u use ax+by =f(x^2)
