discriminant = b^2 – 4ac

a) –25
b) –23
c) 25
d) 26

the solution is the point

step-by-step explanation:

we have

> equation a

> equation b

adds equation a and equation b

substitute the value of x in equation b to find the value of y

the solution is the point

answer: bearing in mind that a rectangle has a perimeter of length + length + width + width.

step-by-step explanation:
