Simplify this rational expression. 2x^2+5x+3/2x^2-x-3

Murljashka [212]

Answer:

$2x+3$ / $2x-3$

Step-by-step explanation:

firstly we make two steps to simplify this question.

1st step: simplify $2x^{2} +5x+3$

to simplify this we use factorization

$2x^{2} +2x+3x+3$

$2x(x+1) +3(x+1)$

$(2x+3) (x+1)$ .....(1)

2nd step:simplify $2x^{2} -x-3$

$2x^{2} +2x-3x-3$

$2x(x+1)-3(x+1)$

$(2x-3)(x+1)$ .....(2)

now dividing (1) and (2), we get the answer

$2x+3/2x-3$

A soccer league has 160 players. Of those players 40% are boys. How many boys are in the soccer league?

MatroZZZ [7]

The answer is 64 boys are in the soccer league.

X/160 = 40/100

X/160 * 100 = 40/100 * 100

5x/8 = 40

(8 * 5x)/8 = 40 * 8

5x = 320

5x/5 = 320/5

x = 64
