Step-by-step explanation:
sum of all interior angles of hexagon=720°
(x+70)°+x°+(2x)°+(2x)°+(2x-10)°+(x+30)°=720°
9x+90=720°
9x=720-90
9x=630
x=70

Answer:
264 Miles
Step-by-step explanation:
Let's imagine that going to the mountains she traveled at x miles per hour. Then according to the problem, on the way home, without traffic, she traveled at x + 22 miles per hour.
We know that the distance is the same in each direction.
If she traveled at speed x for 6 hours going to the mountains, the distance she traveled was 6x.
Coming home she traveled at speed (x + 22) for 4 hours, or 4(x + 22).
But since the distance is the same each way, we can say
6x = 4(x + 22)
Now we can just manipulate the equation to solve for x.
6x = 4x + 88
2x = 88
x = 44.
If x = 44, then her trip to the mountains we 6 hours times 44 miles per hour, or 264 miles.

Answer:
-36
Step-by-step explanation:
We were given the expression as
(c3+d2)
Where our
c=-4
Then d= 10
Then substitute for the values of "c and d" in given expresion, we have
(c3+d2)
(-4)^3 + (10)^2
=-64 + 100
= -36
