If you are solving for a value, you can divide by -1
For example:
-x=5 (divide by -1)
x=-5
If you have an equation, you can negate every part
For example:
-x^2-2x+7=0 (negate)
x^2+2x-7=0
Answer:
x = 7
Step-by-step explanation:
2x + 1 = -3x + 36
2x + 3x + 1 = -3x + 3x +36
5x + 1 = 36
5x + 1 - 1 = 36 - 1
5x = 35
5x/5 = 35/5
x = 7
The answer i got was 31.4.... if that’s wrong i’m so sorry.
Answer:
25π
Step-by-step explanation:
Raidus: 10/2 = 5
Area = πr²
= π5²
= 25π
