Answer:
16sqrt(3) units²
Step-by-step explanation:
This shape consists of 6 congruent triangles
Each angle = (6-2)×180/6 = 120
These are 6 equilateral triangles
6(½ × 8 × 8 × sin(60)) = 16sqrt(3) units²
40 mph
First you have 1200/30. You are trying to get to 1 hour, so in order to get 30 to one, you must divide 30 by 30 and 1200 by thirty as well. You get 40 miles per hour.

Answer:
Step-by-step explanation:
90x - 60y = 68.....multiply by -1
90x - 70y = 91
---------------------------
-90x + 60y = -68 (result of multiplying by -1)
90x - 70y = 91
---------------------------add
-10y = 23
y = -23/10 <===
90x - 60y = 68
90x - 60(-23/10) = 68
90x + 138 = 68
90x = 68 - 138
90x = - 70
x = -70/90
x = -7/9 <=====
Answer:
Because f(g(x)) = g(f(x)) = x, f and g <u>are </u> inverse functions.
Step-by-step explanation:
f(g(x)) = f(
) = 
g(f(x)) = g
