Answer: x = -4, x = 5
Step-by-step explanation:
You can use the substitution method for this problem.
y = 
+ 2x, but y also = 3x +20.
Because of this, you can determine that +2x = 3x + 20 because they are both equal to the same thing, y.
Solve the quadratic equation you got from substitution:
+ 2x = 3x + 20
-x = 20
-x -20 = 0
You can factor this equation:
(x+4)(x-5) = 0
x = -4, x = 5
To find a perfect square we want the equation to look like (y - 8)(y-8) because
the two numbers that add up to -16 and multiply into 64. are -8, -8. -8^2 is 64.
Answer:
false
Step-by-step explanation:
i dont understand kinda
but if you add it,
88<106
so false
Answer: 1/108
Step-by-step explanation:
2^-2 is 1/4
3^3 is 27
1/4 / 27 = 1/108
