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:

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

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

$y=\frac{10}{4*2}*4$ <em> (8=4*2)</em>

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

$y=5$

$\sf{\qquad\qquad\huge\underline{{\sf Answer}}}$

Let's Solve ~

$\qquad \sf \dashrightarrow \: 4 {x}^{2} + 20x + 25$

$\qquad \sf \dashrightarrow \: 4 {x}^{2} + 10x + 10x + 25$

$\qquad \sf \dashrightarrow \: 2x(2x + 5) + 5(2x + 5)$

$\qquad \sf \dashrightarrow \: (2x + 5) (2x + 5)$

$\qquad \sf \dashrightarrow \: (2x + 5) {}^{2}$

$\sf{\qquad \sf \dashrightarrow \: 4x² + 20x + 25 }$

$\sf{\qquad \sf \dashrightarrow \: (2x)² + (2 \sdot 2x \sdot 5) + (5)²}$

[ it's similar to expression - a² + 2ab + b² that is equal to (a + b)² ]

so, let's use this identity here to factorise :

$\sf{\qquad \sf \dashrightarrow \: (2x + 5)²}$
