Answer:

To solve the question the answer is 35y2 - 5 (i think)

Step-by-step explanation:

Yes and it's actually very simple.

To start off:

Simplify the equation: multiply 7 by the numbers in the parentheses getting: 28y2 - 35 .......full equation: 7y2 + (28y2 - 35)

New equation: 7y2 + (28y2 - 35) now combine like terms this means adding each common variable together. in this case, 7y2 and 28y2 would be added together to simplify the equation. Add them together, the new equation is: 35y2 - 5

Lmk if you have any questions i hope this helps

Answer: 1/36

Step-by-step explanation:

Calm down, I'm here to help! You might want to watch some videos on how to solve negative powers, but it's simpler than you think.

An exponent expression is formatted as a^b.

If "b", the exponent, is negative, then you can solve expression like this:

1/a^-b

By writing -b, I mean the opposite of b. For example, the opposite of -2 is 2.

Let's use that rule to solve this problem.

1/6^-(-2)

1/6^2

1/6*6

1/36

There you go! It's not too scary now, is it? Let me know if you'd like me to link some resources!
