Question

Which expression is equivalent to 10x2y + 25x2? 5x2(2y + 5) 5x2y(5 + 20y) 10xy(x + 15y) 10x2(y + 25)

Answer 1

Answer:

we have

$10x^{2}y+ 25x^{2} ||$

we know that

$10=2*5\\25=5*5 ||$

substitute

$(2*5)x^{2}y+ (5*5)x^{2} ||$

$Factor 5x^{2} ||$

$(5x^{2})(2y+ 5) |$

therefore

the answer is

$(5x^{2})(2y+ 5)|$

Answer 2

Answer:

if you expand the question you get 20y + 50, so expanding all the solutions the one that is equivalent is 5 x 2(2y + 5)
