Answer:
There's no h
Step-by-step explanation:
3 + (-1) + (-4)
3 + -1 = 2
2 + -4 = -2
Isn't the formula radius squared? So I'd be 12^2 = 12x12 = 144
Answer: x^2−xy+1
Step-by-step explanation:
simplify:
5+x^2−xy−4
5+x^2+−xy+−4
Combine Like Terms:
5+x^2+−xy+−4
(x^2)+(−xy)+(5+−4)
x^2+−xy+1
I'm guessing you're trying to simplify the equation since there is no other information lol
[(2x+y)-3]
So basically when you are trying to simplify equations you have to add the same variables together (In this case X & Y) But since there are no alike variables there really is nothing to add
So your answer would be 2x+y-3
Hoped this helped
Answer:
x/2 - 12
Step-by-step explanation:
let the number be x
half a number means x divide by 2. i.e x/2
when decreased by 12 means x/2 - 12
