Solve the quadratic equation. 0 = 5x2 - 2x + 6

we have

Group terms that contain the same variable, and move the constant to the opposite side of the equation

Factor the leading coefficient

Complete the square. Remember to balance the equation by adding the same constants to each side

remember that

therefore

the answer is

the solutions of the quadratic equation are

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2

the answers might not be correct use at own risk

you didn't give me the choices, so i will just give you the graph so you can look at your choices and choose the right one.
