Answer:

Step-by-step explanation:
So, our equation is:

In exponetial form, this looks like:

Now lets cube the 5:

Next, we can multiply the denominator on the right side by 5:

We need to now get x alone by adding 4 to both sides:

Finally, we divide by x's coefficent, 2, to get:

Hope this helps! :3
The first and the third one because they equal each other
2x+2=2(x+1) and 3(x-1)=3x-3
Answer:
∠b = 88 - 5x
Step-by-step explanation:
If a and b are complementary, then sum of two angles is 90
∠a + ∠b = 90
5x + 2 + ∠b = 90
∠b = 90 - 5x - 2
∠b = 88 - 5x
