Answer:
yes
Step-by-step explanation:
So basically we have to solve 100 = -x² + 10x + 300 for x.
x² - 10x - 200 = 0
(x - 20)(x + 10) = 0
x = 20, -10
Well the square root of a number is a number times its self equaling the number you're getting the square root of. For example:
<span>√ 25
</span>
To get sqrt of 25 we need to find a number times its self that equals 25. Lets try 8.
8 x 8 = 64
Well thats much too high, We'll try a lower number.
4 x 4 = 16
Just a little higher.
5 x 5 = 25
Since 5 times itself equals 25 that makes it the sqrt.
So, the √ 25 is 5.

Hope this helps
(Also, do you want how the answers came up? If so please comment below this and tell me that. I would be more than happy to write the equations if you want.)
80/16 = x/48
80*48/16 = x
x = 240
