What are the solutions to the equation 3(x – 4)(x + 5) = 0?

Answer:

x=4 and x= - 5

Step-by-step explanation:

In order to solve this we should re-arrange the equation:

$(x-4)(x+5)=\frac{0}{3}$

This is equal to:

$(x-4)(x+5)=0$

Then we can seperate this into:

$(x-4)=0\\(x+5)=0$

So solving for x in both cases we get

$x-4=0 \\x=4\\And\\x+5=0\\x=-5\\$

Answer:

$l=\frac{A-\frac{1}{2} \pi w^2}{2w}$

Step-by-step explanation:

We essentially need to solve for l; in other words, we must isolate it to one side.

First, notice that the term $\frac{1}{2} \pi w^2$ doesn't have any l terms in it, so we can just move this to the left side by subtracting both sides by $\frac{1}{2} \pi w^2$ :

A - $\frac{1}{2} \pi w^2$ = 2lw

Now, the right side has 2lw, so we must divide both sides by 2w to isolate l:

$l=\frac{A-\frac{1}{2} \pi w^2}{2w}$

Noah and Carter are collecting box tops for their school. They each bring in 1 box per day starting on the first day of school

Sedbober [7]

Answer:

Well since they're bringing 1 each day, just multiply that by the number of days of school, or just use the variable x to replace it.

1x = the number of box tops they each bring to school
