Answer:
25x ²−49y ²
Step-by-step explanation:
We need to find product of (5x+7)(5x−7y)
By using identity (a+b)(a−b)=a −b ²
We have a=5x,b=7y
Thus (5x+7y)(5x−7y)=(5x) ²−(7y)

Solving for v and combining like terms:
10 + v - 17v = 4
- v - v
10 - 16v = 4
-10 -10
-16v = -6
/-16 /-16
<u><em>v = 0.375 or 3/8
</em></u>Hope this helps!
