Answer:
a. 6(7) + 2(3)^2 = 60
b. (5(-18)/3)-2 = -32
c. (6(10))^2 - 10/5 = 3598
d. (1-3)(1+2) = -6
Step-by-step explanation:
Answer:
d=(−3−4)2+(−7−(−7))2−−−−−−−−−−−−−−−−−−−−√
d=(−7)2+(0)2−−−−−−−−−−√
d=49+0−−−−−√
d=49−−√
d=7

Answer:
the side length is 30 feet
Step-by-step explanation:
we are given cost equation as
![C=\frac{n^2}{5}+175](https://tex.z-dn.net/?f=C%3D%5Cfrac%7Bn%5E2%7D%7B5%7D%2B175)
where
C is the cost in dollars
n is a side length in feet
we are given
cost is $355
so, C=355
we can set C=355
and then we can solve for n
![355=\frac{n^2}{5}+175](https://tex.z-dn.net/?f=355%3D%5Cfrac%7Bn%5E2%7D%7B5%7D%2B175)
we can subtract both sides by 175
![355-175=\frac{n^2}{5}+175-175](https://tex.z-dn.net/?f=355-175%3D%5Cfrac%7Bn%5E2%7D%7B5%7D%2B175-175)
![\frac{n^2}{5}=180](https://tex.z-dn.net/?f=%5Cfrac%7Bn%5E2%7D%7B5%7D%3D180)
Multiply both sides by 5
![5\times \frac{n^2}{5}=5\times 180](https://tex.z-dn.net/?f=5%5Ctimes%20%5Cfrac%7Bn%5E2%7D%7B5%7D%3D5%5Ctimes%20180)
![n^2=900](https://tex.z-dn.net/?f=n%5E2%3D900)
now, we can take sqrt both sides
![n=\sqrt{900}](https://tex.z-dn.net/?f=n%3D%5Csqrt%7B900%7D)
![n=30](https://tex.z-dn.net/?f=n%3D30)
So,
the side length is 30 feet
