Use the Pythagorean theorem for this. (a^2+b^2=c^2)
a=9, b=12, c=x
9^2+12^2=c^2
81 + 144 = c^2
225 = c^2
c =15
the answer is c
Answer:-3x+6/2
Step-by-step explanation:
To simplify -3/2(x-2)
We get
-3x+6/2
A) 8/40 = 1/5
b) 12/40 or 6/20
c) 26/40 or 13/20
Answer:
x=8/9
Step-by-step explanation:
5x+2(x-3)=-2(x-1)
1) Distribute 2 to x and -3:
5x+2x-6=-2(x-1)
2) Distribute -2 to x and -1:
5x+2x-6=-2x+2
3) Combine alike terms:
7x-6=-2x+2
4) Add 2x to both sides:
9x-6=2
5) Add 6 to both sides:
9x=8
6) Divide both sides by 9:
x=8/9
Answer:
120
Step-by-step explanation:
-5(6) 2(-2)
-5 x6 = -30. 2 x -2=-4
