Answer:
9.4 miles
Step-by-step explanation:
5 ² +8 ² =C ²
25+64=c ²
89=c ²
c=9.4
So for a hexagon, the sum of all interior angles is 720°, all we need to do is add all the angles up and set it to 720 to get angle B.

Firstly, combine like terms to get 
Next, subtract 612 on each side, and your answer should be 
Answer:
Step-by-step explanation:
(f.g)(x) = (x² - 2x + 3) (x³ - 4)
= x²* (x³ - 4) - 2x* (x³ - 4) + 3 * (x³ - 4)
= x²*x³ - x²*4 - 2x*x³ - 2x*(-4) + 3*x³ - 3 * 4
= x⁵ - 4x² - 2x⁴ + 8x + 3x³ - 12
= x⁵ - 2x⁴ + 3x³ - 4x² + 8x - 12
Answer:
50
Step-by-step explanation:
575/11.5=50
Set equal to each other since both equal 90
5x-6y=-10x-6y
add 6y to both sides
5x=-10x
x=0
5(0)-6y=-90
-6y=90
divide by -6
y=-15
(x,y)
(0,-15)
