The answer would be X=10
First you would subtract 2 to -48 and that gives you -50. After you will divide the -5x to -50 and that gives you X=10
It’s an irrational number
Hope this helps!
Answer: 23
If x=-1 then (-1) to the power of 3 = -1 and (-1) to the power of 2= 1
3(-1)^3= -3
2(-1)^2= 2
-3+2+25= 23
