Answer:
(a) isosceles
(b), (c) scalene
Step-by-step explanation:
The lengths of the sides can be found from the distance formula:
d = √((x2 -x1)^2 +(y2 -y1)^2)
Here, there are 9 lengths to be computed, so it is useful to let a spreadsheet or graphing calculator do it.
We find triangle (a) has two sides the same length, so it is isosceles.
The other two triangles have three different side lengths, so they are scalene.

Step-by-step explanation:
Sarah has $55
Her expenses are 3 shirts priced at $m each.
Total cost of 3 shirts at $m each would be the multiplication of each:
3 * m = 3m
The amount of money Sarah has left would be the total she had MINUS what she spent on 3 shirts. That would be:
Remaining Money = 55 - 3m
If 1 candy bar is 32 1/5 then you would multiply 32 1/5 x 33 =1062.6
≈ 1063 calories
