Answer:
-216 x^3
Step-by-step explanation:
(-6x)^3
This is really (-6x)* (-6x) * (-6x)
-216 x^3
Answer:
150
Step-by-step explanation:
The 100% of a number is represented by N and 60% of N = 90
To find the whole we multiply 90 with 100 and divide that by 60
100*90/60 = 150
Basically to solve this, you set both equations equal to each other and solve because the angles are the same.
5x+7=8x-71
isolate x by adding 71 to both sides and subtracting 5x from both sides
3x= 78
divide 78 by 3
x=26
