Step-by-step explanation:
x² + 3x - 15 = 2x - 13
x² + x - 2 = 0
(x + 2)(x - 1) = 0
By zero product rule, (x + 2) = 0 or (x - 1) = 0.
Hence x = -2 or x = 1.
Yes it does.
A and B are *2
That will be C *2 + D *2 is gonna be
a right triangle of 7,24,25
Answer:
a = 1.5
b = 1.75
Step-by-step explanation:
First, we need to solve and replace the result in the initial equation as:
Then, this equality apply only if the coefficient of is equal in both sides and the constant is equal in both sides.
It means that we have two equations:
So, using the first equation and solving for a, we get:
Finally, replacing the value of a in the second equation and solving for b, we get:
