Answer:
X=-1
Y=-9
Step-by-step explanation:
x^2+2x-8
x^2+2x +1 =8+1
(x+1)-9
Yes, because they are similar(or you can call congruent), proved by SAS or simply HL.
There are many equations that has a constant of
proportionality, might want to make it more specific.
Answer:
x = Infinite answers.
y = Infinite answers.
Step-by-step explanation:
x + y = 3
2x + 2y = 6
2x + 2y = 6
2x + 2y = 6
=> Therefore, x and y have infinite values that can fit the equation.
