18 Where do the diagonals of the
parallelogram whose vertices are A(2, 1),
B(11, -1), C(12, 3), and D(3,5) intersect?
A (4,0)
B (5,1)
C (7,2)
D (9,4)

there are many solutions.

step-by-step explanation:

step 1: simplify both sides of the equation.

4x+6=4x^2+10x−4

step 2: subtract 4x^2+10x-4 from both sides.

4x+6−(4x^2+10x−4)=4x^2+10x−4−(4x^2+10x−4)

−4x^2−6x+10=0

step 3: factor left side of equation.

−2(2x+5)(x−1)=0

step 4: set factors equal to 0.

x=-5/2 or x=1

idk u tell me

step-by-step explanation:
