Answer:

Step-by-step explanation:

The answer is 5 because as you can see: 10/8, if you divide the 10 by 2 that would be 5. Same with the denominator, 8 divided by 2 is 4. So, your answer is 5/4. Or 5.

Answer:

The answer is Y=5

Step-by-step explanation:

$\frac{y}{4} =\frac{10}{8}$

$y=\frac{10}{8}*4$

$y=\frac{10}{4*2}*4$ (8=4*2)

$y=\frac{10}{2}$

$y=5$

Can you help me to solve this

Ber [7]

Answer:

$\frac{4a-2}{2a+1}$

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

$\frac{8a^2-2}{4a^2+4a+1}$

= $\frac{2(2a-1)(2a+1)}{(2a+1)(2a+1)}$ ← cancel (2a + 1) on numerator/ denominator

= $\frac{2(2a-1)}{2a+1}$

= $\frac{4a-2}{2a+1}$
