I assume that in this question, you are asked to evaluate the value(s) of r. To answer that question, dividing 1252 by 48 gives us 26.0833 or 26. Mathematically expressing the solution,
26 = 26r^4
Then, divide the equation by 26, giving us 1 = r^4. Evaluate r. This will give us answers of +-1.
The second one is the best answer in my opinion i'm not sure.
8y - 11y + 6
Combine like terms
-3y + 6 is the simplified answer.
You go A to B & B 2A + 8 + B to A&A to B&B to a and then you go see 2D to see 2D to see you today to see 2D which equals a + 8 + 8 + 8 + 8 and that's your answer for this question I know it doesn't look like it makes sense but it's correct I think
