Answer:
Area of Triangle A = 4 cm²
Area of Rectangle = 24 cm²
Area of Triangle B = 4 cm²
Area of Trapezoid = 32 cm²
Step-by-step explanation:
The formula to find the area of a triangle is:
The base (b) is 2 and the height (h) is 4.
Now multiply,
2 times 4 = 8
Then divide,
which equals 4.
So the area of Triangle A and B is 4 cm² because they are the same triangles.
The formula to find the area of a rectangle is: a times b.
a=6 and b=4
Multiply,
6 times 4 = 24
So the area of the rectangle is 24 cm²
The formula to find the area of a trapezoid is:
A=6
B=10
H=4
So now,
6+10=16
16 divided by 2 is 8.
Last multiply,
8 times 4 is 32.
The area of the trapezoid is 32 cm²
Hope this helped! And have a great day!
The expression x=20-3D will present the amount Amy has left after buying D sodas.
Step-by-step explanation:
Given,
Total amount = 20 quarters
Cost of sodas = $0.75 = 0.75*100 = 75 cents
25 cents = 1 quarter
1 cent =
75 cents = = 3 quarters
Amount of D sodas = 3D
Let x be the amount left with Amy.
Amount left = total amount - Amount of D sodas
The expression x=20-3D will present the amount Amy has left after buying D sodas.
