Answer:Add the equations in order to solve for the first variable. Plug this value into the other equations in order to solve for the remaining variables.
No solution
Step-by-step explanation:
For this case we must indicate an expression equivalent to:
By definition we have that the distributive property establishes that:
Then, applying the property to the given expression we have:
Thus, an equivalent expression is:

Answer: 65
Step-by-step explanation:
First you have to multiply. 150 x 0.4 = 60
Then you have to subtract 60 from 150, you get 90. Then subtract 25. 90 - 25 = 65.
Answer:
Positive
Step-by-step explanation:
Since there are two x-intercepts, -2 and 2, there is a positive discriminant. If the parabola was below the x axis and opened downwards, the discriminant would be negative.
