Answer:
D: 6√30
Step-by-step explanation:
Simplify the following:
sqrt(20) sqrt(3) sqrt(18)
sqrt(18) = sqrt(2×3^2) = 3 sqrt(2):
sqrt(20) sqrt(3)×3 sqrt(2)
sqrt(20) = sqrt(2^2×5) = 2 sqrt(5):
2 sqrt(5) sqrt(3)×3 sqrt(2)
2×3 = 6:
6 sqrt(5) sqrt(3) sqrt(2)
sqrt(5) sqrt(3) sqrt(2) = sqrt(5×3×2):
6 sqrt(5×3×2)
5×3 = 15:
6 sqrt(15×2)
15×2 = 30:
Answer: 6 sqrt(30)
For trapezoid, the area = (upper base + lower base) * height / 2
So area = (12 + (2*2 + 12) ) *13 / 2 = 182

m slope
n y-intercept
for:
m = -5
x = -2
y = -6

find n and insert it into the first equation
Hope this helps let me know if you need help
Answer:
the answer would be the first one 321 m^2
Step-by-step explanation:
m=2(wl+hl+hw)=2·(10·6+6·6+6·10)=312
