Replace ∗ with a monomial so that the derived equality will be an identity: (15y + ∗ )2 = 225y²+6x³y+0.04x^6

(I need the answer for this quickly.)

Solve this system of equations. 12x − 18y = 27 4x − 6y = 10

Sundar used linear combination to solve the system of equations shown. he did so by multiplying the first equation by 5 and the second equation by another number to eliminate the y-terms. what number did sundar multiply the second equation by? 2x+9y=41 3x+5y=36
