Answer: .1.) 28.8
9.) 150 ft
8.) 630 ft
10.) 5'10"
Step-by-step explanation:. Ratios set up as fractions. 12/25 :x/60
cross multiply. 12 × 60 = 720. Divide by denominator if left side.
720/25 = 28.88
Answer:
the correct answer is 131
Step-by-step explanation:
5^3 +3(2)
= 125 +6
=131
x(6+7x)
y= -6x+23
perpendicular: opposite signs and reciprocal
m= 1/6 and y-intercept = 23
2i and -2i
I'll change u to x to be easier to understand.
x^2 = -4
sqrt(x^2) = sqrt(-4)
sqrt(-4) = 2i, or -2i
