For these problems you have to use PEMDAS so for problem 15 you would do the parentheses first, (21-3) you get 18 and then exponents, 3^2, you get 9, no multiplication but there is division so take your answers, 18 and 9 and divide them, you get 2, so the answer to 15 is 2.
Answer:
25
Step-by-step explanation:
x^2=24^2+7^2
=576+49
=625
x=25

Answer:
10n-13
Step-by-step explanation:
n is positive and 9n is positive so you add 9n and n
9n+n=10n
10 is negative and so is 3 so you do negative 10 minus 3
-10-3=-13
10n-13
Answer:
I believe the answer will be 63 degrees not 100% sure tho
Step-by-step explanation:
The reason is because triangle FHE measures 27 degrees it looks like FHE is a right triangle so there needs to be a total of 90 degrees in a right triangle so 90-27=63 like I said not 100% correct
