Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable.
<em>(I dunno if you know how to find the area of the trapezoid, so I included this wordy directions) </em>
Add the top/first base plus the second/bottom base together.
Multiply that with the height.
After, divide that by two.
3 cm + 6 cm = 9 cm
9 cm x 4 cm = 36 cm
36 cm /2 = 18 cm
Area of trapezoid: 18 cm^2
So using the given information about (original) larger area of trapezoid being 72 cm^2,,,
,,,we would get 1/4 if we divide 18/72.
(scale factor)^2 = (1/4)
= 1/2
<h2>ANSWER: Scale factor is 1/2</h2>

a:
Just divide both sides by 7. Since 7 is positive, you don't need to change the inequality sign:
In set notation, we write
b:
Subtract 9 from both sides:
In set notation, we write
Answer:
1
Step-by-step explanation:
use PEMDAS=
2+6=12
12x2=24
48/24=2
2-1= 1
