Answer:
I think its 3, but if I'm wrong I'm so sorry!
Step-by-step explanation:
Well, the exponent is distributed to the 6 and g.
g cannot be changed and therefore remains as 
can be simplified even further and into the number 216
Therefore, your answer should be:
Answer: 5x
Step-by-step explanation:
5x + 3x = 8x
The answer is 90, Because angle D is a 90 degree angle, and 180- 90=90, so the answer is 90.
Answer:
{y,x} = {-6,-2}
Step-by-step explanation:
/ Solve equation [2] for the variable y
[2] y = 2x - 2
// Plug this in for variable y in equation [1]
[1] (2x-2) - x = -4
[1] x = -2
// Solve equation [1] for the variable x
[1] x = - 2
// By now we know this much :
y = 2x-2
x = -2
// Use the x value to solve for y
y = 2(-2)-2 = -6
