Hey there! I'm happy to help!
We see that at AB is halfway across our line. We see that AC is the total line.
So, to find the other half, we have to subtract AB from AC, which will give us the value of BC.
We first will subtract our x values.
3x-x=2x
And then we subtract our numbers.
-6-5=-11
So, BC is 2x-11.
Have a wonderful day and keep on learning! :D
<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>

$96
48/12= 4
4*24=96
48 headbands will cost $96
Volume of cone = (1/3)pi*r²h
56.52 = (1/3)*3.14*r²*6
56.52/(2*3.14) = r²
9 = r²
r² = 9
r = √9
r = 3
Diameter = 2*r = 2*3 = 6 inches. b.
