Answer:
x = -4 and x = -14
Step-by-step explanation:
Our equation is (x + 9)² = 25
Applying the square root property we would need to take the square root of both sides: 
This give us x + 9 = ±5
Here we have two equations since taking the square root gives us a positive and negative value
Our first equation is x + 9 = 5, and to isolate the variable we would need to subtract 9 from both sides, giving us x = -4
Our second equation is x + 9 = -5, and to isolate the variable we would need to subtract 9 from both sides, giving us x = -14
I dont think so. and you should add and then reseporate the groups.
Answer:
It would be 90
Step-by-step explanation:
If you look at it you can see it is a right angle. And a right angle is always 90 degrees. Hopes this helps and have a nice day and stay safe
3+2x=y
6y=5x+4
6(3+2x)=5x+4
18+12x=5x+4
14+12x=5x
14=-7x
-2=x
the number is -2
