Answer:
Step-by-step explanation:
Let |x-a|=b
then x-a=±b
so x-a=b
or x=a+b
so a+b=18 ...(1)
and x-a=-b
or x=a-b
or a-b=8 ...(2)
adding (1) and (2)
2a=26
a=26/2=13
subtract (2) from (1)
2b=10
b=10/2=5
|x-13|=5
X jumpers at <span>£15 each. Total = 15*x = </span><span>£15x
</span>
y shirts at £12 each. Total = 12*y = <span>£12y
Total cost = </span><span>£15x + </span><span>£12y
Total cost = </span><span><span>£(15x + 12y)</span></span>
Answer:
12
Step-by-step explanation:
The area is 24 square inches. So its dimensions in inches
must be factor-pairs of 24 .
Those are
1 x 24
2 x 12
3 x 8
or
4 x 6 .
