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

80x^8−68x^6+16^5−20x^4−4x^3+8x^2

hope i'm right lol

im guessing (23,14). hope this : )

1 ?

step-by-step explanation:

u said 1+1+1+1+1+1+1+1+1+1+1+1*0 so ur adding 1 but then multiplying by 0 so its 0 but then u said 1*0+1 so now ur adding 1 so the answer is juan ?

~leah

t= half of the arc subtended by t.

r= half of the arc subtended by r.  

t+r= half of the arc subtended by t + half of the arc subtended by r= half of 360=180
