Answer:
11
Step-by-step explanation:
1) lets get rid of the parentheses, we dont really need them:
−22 −4 + 8+ 52 + 2 − 25
Following order of operations we need to work from left to right
so
-22-4=-26
-26+8=-18
-18+52=34
34+2=36
36-25=11
the answer is 11
hope this helps

Step-by-step explanation:
a^2+6^2 = 23^2

a^2 = 529 - 36
a^2 = 493
a = √493
a = 22,20
