Scaling triangle ABC with a scale factor of 2 will result in the image A'B'C' having sides which are twice the size of the sides of ABC.
Let the size of the sides of ABC be x, y and z, then the perimeter of ABC is x + y + z.
Dilation of ABC with a scale factor of 2 will result in the image A'B'C' with sides, 2x, 2y, and 2z, with perimeter 2x + 2y + 2z = 2(x + y + z) = 2 times the perimeter of ABC.
We will need to use a systems of linear equations here. Firstly, we will use x for cans of peas and y for cans of corn. This is kind of difficult to explain, but basically, our first equation is going to be the amount x and y costs. Therefore, 0.85x + 0.78y = 6.59. This works because we need to find out how much cans she bought of each.
Next, we know that she for 2 more cans of peas than cans of corn. We can use the equation, 2 + y = x, to represent this situation. This is because she purchased two more cans of peas, so we add 2 to y (cans of corn).
Our equations are: 0.85x + 0.78y = 6.59, 2 + y = x

If the original price tag of the video game is $128, to get its discounted price at 15%, that means what Leiff paid for was (100-15) = 85% of the original price.
So, the price of the video game then becomes
(0.85 x 128) = $108.80.
Since Leiff has to pay an additional 5.3% of the new price, that's (100 + 5.3) = 105.3% of the new price which is
(1.053 x 108.8) = $114.57
Adding the shipping fee for the videogame,
114.57 + 4.75 = $119.32
Thus, the total price is <span>$119.32</span>
let's recall that an equilateral triangle has all interior angles of 60°.
Check the picture below.
so as you can see, 2√3 = x = r, namely the radius of the circle.
