Answer:
see the explanation
Step-by-step explanation:
we know that
If the absolute value of the scale factor is less than 1, then the dilation produces a contraction of the original image
If the absolute value of the scale factor is greater than 1, then the dilation produces an expansion of the original image
so
<u><em>Verify each value</em></u>
1) -4


therefore
The dilation produces an expansion of the original image
2) 0.25


therefore
The dilation produces a contraction of the original image
3) -2/3


therefore
The dilation produces a contraction of the original image
4) 2.3


therefore
The dilation produces an expansion of the original image
Answer:
b
Step-by-step explanation:
Answer:Area of wall =

ft
Explanation:First, we know that:1 in = 1/12 ft
Therefore, the dimensions of the wall would be as follows:H = 7 ft 10 in =

ft
B1 = 10 ft 2 in =

ft
B2 = 14 ft 1 in =

ft
For the trapezium, area can be calculated using the following the following formula:Area of trapezium = Average base * height =

* height
Substitute with the given to get the area as follows:Area of wall = ([

+

] / 2) *

Area of wall =

ft
Hope this helps :)
