help!
@AP @RichardWatterson7
The first one I believe
It's not the first one.
@Cupcake123456 Do you know what an equilateral triangle is?
yeah
How many sides does it have?
3
and they are all equal to each other
Do you know what the perimeter is?
yeah they equal 60
@Cupcake123456 How do you get the perimeter of any shape?
add up each side ?
or do i multiply ?
Correct. So if you need to add up all the sides, which is three of them, and they are equal, and the total perimeter is (15x + 30)...how could we get the value of each side...
i dont understand what u just said ?^
If it helps, think of an equilateral triangle with a perimeter of 3.
What is the value of each side
60?
no, I think you are thinking about angles.

The measure of each angle in an equilateral triangle is 60. But, we want the sides. So if I add up all the sides, which are three, and each side is equal in length, and I get a value of 3, what must be the value of each side?
180 degrees ?
That is the angle
i DONT UNDERSTAND THIS AT ALL !
|dw:1542315289689:dw|
The value of the angles, are 60. The value of the sides, is 1
ill just come back to that question later its aggravating me !
Do you know the difference between an angle and a side?
unless u still wanna help
yeah i was just confused
Yeah so, perimeter is adding up the sides, not the angles
Look at my example. It's an equilateral triangle so all the sides are equal in length. A triangle has three sides, so we have three sides that all have the same length. So if the total perimeter is three, I can divided by 3 (the total number of sides) to get the value of each side.
Which is 1..
OK>>
So try and see how I solved my example, then look at how you'd solve your problem. Trust me, it is very simple. If you are confused, just let me know. I am here to help.
would it be C ?
How'd you get that?
i guessed
or b ?
okk...
\[P = (15x + 30) \rightarrow \frac{ 15x + 30 }{ 3 } \rightarrow S = 5x + 10\] Perimeter is 15x + 30 Divide it by 3, you get the value of each side
so c ?
