The answer would be n+n+2/2n+2 as Jide is n and his twin sister is two years older so she would be his age (n) plus 2 so n+n+2=2n+2

A nice trick i use for word problems is that i highlight the numbers and what they are, like: liters, kilograms, grams, etc. say this is your word probem:

Suzie made 30 kilograms of party mix chips and 40 liters of punch for her party, Suzie had 20 people at her party, how much punch and party mix chips will there be when the party is over?

I highlighted what i would have highlighted if it was a real word problem.

Good luck! Hope my trick works for you too!

(2x-7)-(4x^2+6x-3)+(x^2+4)

masha68 [24]

Answer:

$-3x^2-4x$

Step-by-step explanation:

Simplify:

$\left(2x-7\right)-\left(4x^2+6x-3\right)+\left(x^2+4\right)$

$=2x-7-\left(4x^2+6x-3\right)+x^2+4$

Group same factor:

$=-\left(4x^2+6x-3\right)+x^2+2x-7+4$

Add :

$=-\left(4x^2+6x-3\right)+x^2+2x-3$

Apply the distributive law: -(a+b) = -a - b

$-\left(4x^2+6x-3\right)=-4x^2-6x+3$

$=-4x^2-6x+3+x^2+2x-3$

Group same factor:

$=-4x^2+x^2-6x+2x+3-3$

Subtract:

$=-4x^2+x^2-6x+2x$

Add:

$=-3x^2-6x+2x$

Group same factor:

$=-3x^2-4x$

Hence answer = $-3x^2-4x$
