Question

Need an explanation with answer?

Answer 1

Answer:

C) 14y² = 2y(4y) + 6y²

LHS. RHS

14y². (2y X 4y) + 6y²

8y² + 6y²

14y²

Therefore ,

LHS = RHS

14y² = 14y²

Hence proved

please mark me as brainliest

Answer 2

Answer:

for option a 3x+9x+5x=17x is not equal to 27x^2+5x

b)2z+3z×3z=2z+9z^2 is not equal to 18z^3

c)2y×4y+6y^2=8y^2+6y^2=14y^2

d)5w (2w+3)+2w=10w^2+17w is not equal to 10w^2+17w^2=27w^2

hence option c is correct
