First simplify the number part, 14/2 = 7/1
then the x part,

y doesn't need to be simplified
then simplify the z part, z^-6 = z^6
put it all together...
Answer:
yes it is because they are both going by two
Step-by-step explanation:
Answer:
A
Step-by-step explanation:
4(x+3)+3(5-x)
=4x+12+15-3x
=x+27
Answer:
Step-by-step explanation:
For each problem you need to make sure that the angles are the same.
So x + 22 = 90
x = 90 -22 = 68 degree
For the second problem
7x + 10 = 8x
10 = 8x -7x
x = 10 degree
