Answer:

B. 7(x − 5)(y + 2)

Explanation:

A. 7(2x − 5)(y + 2) = 14xy + 28x − 35y − 70 (Wrong)

B. 7(x − 5)(y + 2) = 7xy + 14x − 35y − 70 (Correct)

C. 7(x − 2)(y + 5) = 7xy + 35x− 14y − 70 (Wrong)

D.  7(x − 10)(y + 2) = 7xy + 14x − 70y − 140 (Wrong)

2nd one

Let's verify

[tex]\\ \rm\Rrightarrow 7(x-5)(y+2)[/tex]

[tex]\\ \rm\Rrightarrow 7(xy-5y+2x-10)[/tex]

[tex]\\ \rm\Rrightarrow 7xy-35+14x-70[/tex]
