Difference of 2 perfec squares is
(a^2)-(b^2)
if the exponents are both even and the coeficient (the number in front) are perfect squares, then it is difference t 2 perfect squares
first one
8 is not perfect square
2nd one
(4e^4)^2-(9g^2)^2
third
25 is odd, so it cannot be split up into 2 nice numbers
4th
(11m^9)^2-(3n^5)^2
The answer is 33
Step-by-step explanation:
56-23=33
So we know the gym charges $10 to join, and the $4 every visit. He wants to visit 20 times, so we multiply 20 by 4 to get the price of 20 visits, which is $80. Then we add $10 for the joining fee. The total will cost him $90. That means he needs to save $44 to visit 20 times. Hope that helps!
