Matilda uses the polynomial identity (2x−y)^2=4x^2−4xy+y^2 to show that 18² = 324. What values can Matilda use for x and y?

A . x = 10 and y = 2
B x = 2 and y = 20
C. x = 2 and y = 10
D. x = 20 and y = 2

the answer is d

the answer is in the first quadrant, which make the y-int positive.

since the dots are going down, therefore the correlation is negative

i hope it is right.

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.
