After subtracting 3 from 7, and dividing 4 by 2, you should end up with x=2.
Each qt has 2 pts in it.
13 qts add up to 26 pts.
That's more than 25 pts.
Answer:

Step-by-step explanation:
Factorise the numerator and denominator
8a² - 2 ← factor out 2 from each term
= 2(4a² - 1) ← 4a² - 1 is a difference of squares
= 2(2a - 1)(2a + 1)
4a² + 4a + 1 ← is a perfect square
= (2a + 1)²
Thus

=
← cancel (2a + 1) on numerator/ denominator
= 
= 
Answer:
0.5×2/2=1/2 is the required fraction.
