Answer:
its a 30% increase
Step-by-step explanation:
If 250 is 100% then you need an increase by 75 to get to 325
250*.3 = 75
75 is 30% of 250
250 + 30% (75) = 325

Answer:
![\frac{4a-2}{2a+1}](https://tex.z-dn.net/?f=%5Cfrac%7B4a-2%7D%7B2a%2B1%7D)
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
![\frac{8a^2-2}{4a^2+4a+1}](https://tex.z-dn.net/?f=%5Cfrac%7B8a%5E2-2%7D%7B4a%5E2%2B4a%2B1%7D)
=
← cancel (2a + 1) on numerator/ denominator
= ![\frac{2(2a-1)}{2a+1}](https://tex.z-dn.net/?f=%5Cfrac%7B2%282a-1%29%7D%7B2a%2B1%7D)
= ![\frac{4a-2}{2a+1}](https://tex.z-dn.net/?f=%5Cfrac%7B4a-2%7D%7B2a%2B1%7D)
