Well, we would solve it as cancelling out -1/2 by multiplying it by its reciprocal (-2/1) to get x by itself, and now we'll do the same on the other side, where 6/1 times -2/1 = -12/1, which is the same as -12.
So x = -12 :3
Answer:
2, 3, 5
Step-by-step explanation:
9 x 2= 18
9 x 3 = 27
9 x 5 = 45
Minus 4x^2 both sides
25y^2=100-4x^2
divide both sides by 25
y^2=4-4x^2/25
I think 20 Did you try googling it?
Answer:
X to the second power + 5x + 6
Step-by-step explanation:
distribute (X + 2) and (X + 3)
you should get X to the second power + 3x + 2x + 6
then you add like terms (3x + 2x)
then you should get X to the second power + 5x + 6
