<span>I think you meant 6x²+13x-5 so first thing we have to do is factor it which is really quite tricky with this kind of trinomial so first take ac which is 6 times -5 so -30 now figure out factors of -30 that will add up to 13 how about 15 and -2 now that we have the factors write the equation again</span>

<span /><span> 6x²+15x-2x-5  </span>split the equation in half<span />

<span>6x²+15x   -2x-5 so out of the first equation we can pull a 3x out</span>

<span>3x(2x+5) and out of the second we can pull a negative 1</span>

<span>3x(2x+5) -1(2x+5) rewrite it</span>

<span>(3x-1)(2x+5) so the 3x-1 is the factor we already had so the other side is (2x+5)</span>

<span>
</span>

<span><u>HOPE THIS HELPS!!!</u></span>

There are
Andrew [12]

Answer:

40%

Step-by-step explanation:

If there are 1200 students in the school and 720 of them are boys that means 480 of them are girls.

I like to do cross multiply and divide so the equation for that would be  480/120 = ?/100

if you cross and multiply 480 by 100 you will get 48000 then if you divide that by 1200 you will get 40 as your missing value.

Im basically just saying 480/1200 = 40%

If you need further help there are plenty of you tube videos on how to cross  multiply and divide

Hope this helps
