Step-by-step explanation:
it is 6/6
if it is right brainliest pls thanks
I think it might be 7 don't know what answers you may have but its a guess
a^2 - b^2 = (a + b)(a - b)
In this case
49x^4y^2 - 4z^2
= (7x^2y)^2 - (2z)^2
= (7x^2y + 2z)(7x^2y - 2z)
Factors are (7x^2y + 2z) and (7x^2y - 2z)
Answer:
D) 7x^2y + 2z
Minus 9 from both sides
7x = 49
X = 7
