- /-49
-/-1 * 7 * 7
-7i
4 - 3i
Go to 4 on the x axis (right)
Go to -3i on the y axis (down)
Your coordinate is (4, -3i)
To graph -3i, it is like 0 - 3i
Your coordinate is (0, -3i)
so for A it is 16 times as large because the area is 3*3 which is 9 but since it is a triangle the area is halved and is 4.5 and divide 72 by 4.5 which gives us 16
then for b I believe that the scale factor is 4
and for C it is asking for the bottom side of the scaled copy not of triangle A and 4*3=12 so the bottom is 12
ok now its complete =)
3x1,789=5367. as for y 3 digit number is like multiplying a 4 digit number, it's basically the same thing just one digit more.
Find the area of the base:
(4)(3) = 12sqft
Find the area of the sides:
(4)(12) = 48sqft
There are 2 bases and 4 sides, therefore:
12(2) + 48(4) = 24 + 192 = 216sqft
Hope this helps :)
