Answer:

Step-by-step explanation:

$x^{2} -y^{2}$ = (x + y)(x - y)

So, if x + y = 7/10, and x - y = 5/14, $x^{2} -y^{2}$ = (7/10) * (5/14) = 35/140 = 1/4.

(1/2)^2 = 1/4

So, (B) (1/2)^2 is your answer!

Hope this helps!

Multiply both sides by -4/7
$x = 40 \times ( \frac{ - 4}{7} ) \\ x = \frac{ - 160}{7}$
