28. This equation satisfies the condition
-x - 10 = -17
29. You can use this equation
x/5 + 5 = 0
30. The error is dividing the equation first by 3. The solution should have been
3x + 2 = 15
3x = 15 - 2
3x = 12
3x/3 = 12/3
x = 4
31.
x/4 - 6 = 2
x/4 = 2 + 6
x/4 = 8
x = 8(4)
x = 32

<u>c.)44 kilometers</u>
Answer:
Solution given:
let
length =L
and
Area =A
Now
we have
Area [A]=1936 square kilometers
now
As we know that
Area of square :length *length
A=l*l
A=l²
Substituting value of A
1936=l²
doing square root on both side
we get
l=
l=2*2*11
l=44 kilometers
So
<u>the length of one side of a </u><u>square</u><u> </u><u>is</u><u> </u><u>4</u><u>4</u><u> </u><u>kilometers</u><u>.</u><u />
