Answer:
144
Step-by-step explanation:
12X12 is also 12+12+12+12+12+12+12+12+12+12+12+12
Lets simplify that though.
12(10)+12(2) (since 10 plus 2 is 12)
120+24
144
Answer:
13
Step-by-step explanation:
-2 + 15 = 13

Answer:
Step-by-step explanation:
y = 7, so we have:
The scale factor used to create the dilation is 3
You can easily find out by counting the sides
The coordinates of the pre-image are
(-2,-1) , (-2,1) , (-5,1)
the vertical line counts to 2 boxes
the horizontal line counts to 3 boxes
The coordinates of the image are
(4,-1) , (4,5) , (-5,5)
the vertical line counts to 6 boxes
the horizontal line counts to 9 boxes
= 3
= 3
The scale factor is 3
X = 15
y = 21
First, solve for x on the right side triangle by adding angles and equaling to 180.
Now since you know the x value, solve the middle angle for the left side triangle. Add all angle on left triangle and equal them to 180.
