The complete question in the attached figure
we know that
length side AB=8 units
length side DE=4 units
[ABC]=[DEF]*[scale factor]
then
[scale factor ]=[ABC]/[DEF]---------> 8/4--------> 2
the answer is
the scale factor for a dilation image of DEF to obtain ABC is 2
Answer:
The perimeter of the garden, in meters, is 
Step-by-step explanation:
Diagonal of a square:
The diagonal of a square is found applying the Pythagorean Theorem.
The diagonal of the square is the hypothenuse, while we have two sides.
Diagonal of 12m:
This means that
, side s. So





Factoring 72:
Factoring 72 into prime factors, we have that:
72|2
36|2
18|2
9|3
3|3
1
So

So, in simplest radical form:

Perimeter of the garden:
The perimeter of a square with side of s units is given by:

In this question, since 

The perimeter of the garden, in meters, is 
Answer:
y= -5/2x -1
Step-by-step explanation:
7 books costs $14, etc. We have points in a line
(7,14)
(8,16)
(9,18)
They're all points on the line y=2x which just means it costs $2 a book. So 1 book costs $2, 2 cost $4, and 3 cost $6. We have three new points:
(1,2)
(2,4)
(3,6)
They're all on the same line, y=2x, just closer to the origin than the first three. We plot a point at x=1, y=2, etc.

Answer:
Step-by-step explanation:
Power: 3 ^ 3 = 27
Multiple: 2 * 27 = 54
Subtract: -9 - 5 = -14
Power: (-14) ^ 2 = 196
Subtract: 54 - 196 = -142
Compare: = (-142)
