Answer:

ABC dilated
Step-by-step explanation:
Given
Triangles ABC and DEF
Required
Determine the scale of dilation
First, we pick a side on ABC

Pick a corresponding side on DEF

The scale factor is then calculated as:


i.e. ABC was dilated by 1/2
I would say c but that is just a guess
Answer:
She will need 4 square and 8 triangular pieces.
Step-by-step explanation:
For every 6 pieces of cloth, 2 are squares.
So, for 12 pieces of cloth, the no. of square pieces would be,

= 
= 4
As the remaining pieces will be triangles, so the no. of triangular pieces will be, equal to,
(12 - 4) = 8
Answer:
4
units
Step-by-step explanation:
The given shape is a right triangle and in right triangles the sum of square length of legs is equal to square length of hypotenuse (represented with x in here):
12^2 + 32^2 = x^2
1168 = x^2 find the root for both sides
4
=x
Answer:
x=40/9
Step-by-step explanation:
(2/5)*x-((5/8)*x)-15+16=0
(2/5)*x+(-5/8)*x-15+16=0
1-9/40*x=0 // -1
-9/40*x=-1// : -9/40
x= -1/(-9/40)
x=40/9
x=40/9
