As waiwai993 answered, Can/May/Will have different meanings. However asking someone if they can help you usually implies that you would like their help, and it gives the person an opportunity to decline without being rude. Maybe they are able to help in theory, but can't right now because they are too busy. In that case they can say that they can't help. If they simply don't want to help they can just decline without a reason. So I would always use "Can you help me with this" or "Could you help me with this" unless I needed a more specific case (such as I KNOW that they CAN, but I am forcing to answer whether they WILL or not, or I know that they are ABLE, but maybe their mother won't let them*).

Step-by-step explanation:

Find the area of ABC<br>Help
Katarina [22]

The value of the scale factor is 3. Then the height and area of the triangle ΔABC will be 9 ft and 54 square ft.

<h3>What is dilation?</h3>

Dilation means the changing of the size of the object without changing the shape. The size of the object may be increased or decreased based on the scale factor.

The area of the triangle ΔDEF is 6 square ft. And the base length of the triangle ΔDEF is 4 ft.

The area of the triangle is given as

\rm Area = \dfrac{1}{2} \times bh\\\\

Then the height of the triangle ΔDEF will be

\rm 6 = \dfrac{1}{2} \times 4 \times h\\\\h = \dfrac{12}{4}\\\\h  = 3

Then the scale factor will be

\rm SF = \dfrac{12}{4} = 3

Then the height of the triangle ΔABC will be

\rm \dfrac{H}{3} = 3\\\\H \ = 9

Then the area of the dilated triangle ΔABC will be

\rm Dilated \ Area = \dfrac{1}{2} \times 12 \times 9\\\\Dilated \ Area = 54 \ ft^2

More about the dilation link is given below.

A polygon has an area of 225 square meters. If the area is tripled, how does each side length change?
krok68 [10]
Let me tell you the process so that you get to the answer
Remember first that the area of a regular polygon with x sides has  each of them a length which can be represented by y 

<span>A = 1/4 * xy^2 * Cot(180/x) </span>
<span>The purpose is to solve for y, so we get </span>
<span>y^2 = 4A/(xCot(180/x)) </span>
<span>y = √(4A/(xCot(180/x)))

The thing we need to change is A in the previous formula and with that we can use the equaation to be a constant. This could be represented by Z
</span><span>Z = √(4/(xCot(180/x)))
so
</span><span>Y = Z√A 
</span><span>If we increase area by a factor s, y increases by a factor of √x.
</span>So if you want to know the triple then you need to increase it by <span> √3 </span> <span>  </span>

How do you determine if the line segments are congruent
Gemiola [76]
You must calculate the length of the segments.

Suppose segments AB and CD
Being A (m, n), B (p, q)  C(r,s) and D(t,u)
<span>
They are congruent if:

</span>\boxed{(p-m)^2+(q-n)^2=(t-r)^2+(u-s)^2}<span>
