Answer:
No solutions, 0
Step-by-step explanation:
When you solve a equation and get an answer of n = s (I am just using n and s a placeholders. They that be any number.) where n ≠ s, then there are no solutions to the equation.
Answer:
hello hi hello hi hello hello
The side lengths could be 4 in. x 16 in. because that equals 64 inches^2. It could also be 8 in. x 8 in. because that also equals 64 inches^2.
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
