Answer:
Step-by-step explanation:
This problem is all about bases and exponents. Because we have a quotient and the bases are both 5's, that means that we can use the rule of exponents for quotients to rewrite and simplify:
That's the simplification as long as you are "allowed" to leave the exponent as a negative number.
The sum of polynomials involves adding the polynomials
The other polynomial is 
The sum of the polynomials is given as:
One of the polynomials is given as:
Represent the other polynomial with Q.
So, we have:
Substitute the expressions for P and Sum
Make Q the subject
Evaluate like terms
Hence, the other polynomial is

Answer:
12
Step-by-step explanation:
If (2x+8)2 = 64, then I would solve it by making sure the numbers in the parentheses equal 32. This is because it would get multiplied by 2 after you find the answer and 32 x 2 is 64. So what times 2 is 24? 12. 12 x 2 is 24, plus 8 is 32, and multiply 32 by 2 and you get 64 :) I'm not the best at explaining btw ;-;
You must multiply 2.5 by 7 to get the answer which is 17.5 pounds
