Answer:

x = -5, x=8

Step-by-step explanation:

0 = x^2 – 5x – 24

Factor

What 2 numbers multiply to -24 and add to -5

-8*3 = -24

-8+3 = -5

0= (x-8) (x+5)

Using the zero product property

x-8 =0   x+5 =0

x=8     x=-5

If a triangle has side lengths of 5.6 yards, 7.1 yards, and x yards, find the range of possible values of x.
ANTONII [103]
Hi!

To find the range of possible values of x, we have to side 1 from side 2...

7.1 - 5.6 = 1.5

The smallest side x could be is 1.5.
Now add side 1 to side 2

7.1 + 5.6 = 12.7

The biggest side x could be is 12.7

So x could be anywhere from 1.5 to 12.7 (or, 1.5 < x < 12.7)

Hope this helps! :)
