1) 75
2) 30
3) 30m
a) cost for m hours of gym services without the base fee
b) the base fee for the gym membership
c) the fee for one month of membership without the base fee
d) the amount of money the gym charges per month

We are given the equation 75 + 30m which represents the charge in the gym where m is the number of months. In this case, 75 is the base fee for the membership, 30 is the fee for one month of membership and 30m is the cost of m hours without the base fee.

Okay so for every triangle has three angles that always add up to 180 degrees. and to tell the difference between whether they are secure, right or obtuse is that acute: has one angle that is less than 90 degrees. right triangle means there is at least one angle that is exactly 90 degrees. and an obtuse angle has an angle that is bigger than 180 degrees. i’ll do #13 as an example: 13. 40 and 50 so if every triangle has 180 degrees 40+50= 90 degrees then180-90= 90 degrees so the third angle is 90 degrees and because this triangle has a 90 degree angle it means it is a right triangle
