Give the values of a, b, and c needed to write the equation's standard form.(5 + x)(5 - x) = 7A = 1; B = 0; C = -18A = 25; B = 0
1 answer:
We need to FOIL that out and then get it into standard form to see what our A, B, and C are. FOILing gives us 
. If we move the 7 over by subtraction and set it equal to 0, we have 
. In order to avoid a negative leading coefficient, we can change all the signs to get 
so A = 1, B = 0, C = -18, first choice above.

The system of equations is
To find:
The true statement about the given system of equations.
Solution:
The slope intercept form of a line is
Where, m is the slope and b is the y-intercept.
We have,
On comparing these two lines with slope intercept form, we get
Since the slopes of the lines are equal but the y-intercepts are different, therefore, the two lines are parallel and the system has no solution.
Therefore, the correct option is A.
