What is the range of possible sizes for side x?

x = 3.96

Step-by-step explanation:

To find the missing side length you'll need the formula a^2 + b^2 = c^2

a and b would be the shorter ends, 2.8 and 2.8

c would be the longer end that's opposite the right angle.

so substitute values

2.8^2 + 2.8^2 = c^2

7.84 + 7.84 = c^2

15.68 = c^2

√15.68 = √c^2

3.959797 = c

c = 3.96

side c would be side x so x is 3.96

length=4

width=30

Step-by-step explanation:

length=x

width=8x-2

(8x-2)*2+2x=68

16x-4+2x=68

18x=72

x=4 (Length)

4*8=32, 32-2=30(width)
