To find the perimeter it is 2 X Width + 2 X the length = 84
32+ 2 X the length = 84
2 X the length = 52
Therefore the length is 26cm
Midpoint formula
mid of (x1,y1) and (x2,y2) is

so
(22,15)=

therefor
22=

and
15=

slv each
22=

times both sides by 2
44=18+x1
minus 18 both sides
26=x1
15=

times both sides by 2
30=6+y1
minus 6
24=y1
the other point is (26,24)
Answer:
The answer to your question is x ≠ -10 x ≠ 2 x ≠ -2
Solution
Step-by-step explanation:
Process
1.- Factor all the polynomials
= 
2.- Invert the second term
= 
3.- Simplify
= 
4.- x must be different to
x ≠ -10 x ≠ 2 x ≠ -2
This values are from the factor expressions and then equal to zero.
A bag holds 10 apples. The orchard sells 2430 apples in all. Divide the total by the part
2430/10 = 243
243 bags were used and sold.
hope this helps
