So we just need to round all the numbers to the nearest hundred and add.
391 --> 400
221 --> 200
16 --> 0
So 400+200+0=600
Hope this helps! If you have any questions just ask!
Answer:
From the given figure:
Labelled the triangle as A, B and C.
Coordinates of triangle are:
A(-3, -2) , B(-7, -3) and C(-4, -5)
The rule of dilation with scale factor k = 3 and centered at (-7, -6) is:
or
Now, find the dilated image of the given figure:
You can see the graph of the dilated figure as shown below.
He had a profit of $2. Made a $1 each time he sold it.
Ok, well a square is basically two triangles, right? the 45 degree right triangle. if you consider the rules for a 45 degree right triangle, you get: x, x, 2sqrt(x)
plugging in 8, you get the diagonal to be 2sqrt(8) or 4sqrt(2)
