Answer:
The length of the bottom side of the banner is 17 in.
Step-by-step explanation:
Given,
Area of the Banner =
Height of the Banner = 24 in
Top side of the Banner = 14 in
We have to find the length of the bottom side of the banner.
Solution,
Let the length of the bottom side of the banner be 'x'.
Since the banner is in the shape of trapezoid.
So according to the formula of area of trapezoid, which is;
Area of trapezoid =
Here top and bottom sides are parallel and distance between them is equal to the height of the banner.
Now substituting the values, we get;
Hence The length of the bottom side of the banner is 17 in.
need the arctan of the 2 lengths given
9/12 reduces to 3/4
arctan on the calculator is tan^-1
arctan(3/4) = 36.86989 degrees
round off the answer as needed
2x+3(x-2)-3(x-6)
You would first distribute.
So:
2x+3x-6-3x+18
Then you would combine like terms, like so:
2x+3x-3x= 2x
-6+18= 12
So it'd be:
2x + 12
Which is answer choice A

Answer:
So if I multiply those two expressions together, I will get eleven copies
Area of a rectangle = W X L
Area of a rectangle = 5 X 2
Area of a rectangle = 10
Area of triangle 1= 1/2 X B X H
Area of triangle 1= 1/2 X 2 X 2
Area of triangle 1= 1/2 X 4
Area of triangle 1= 2
Area of triangle 2= 1/2 X B X H
Area of triangle 2= 1/2 X 7 X 4
Area of triangle 2= 1/2 X 28
Area of triangle 2= 14
Area of a rectangle + Area of triangle 1 + Area of triangle 2=
10 + 2 + 14 = 36
