Answer: The area is 
Step-by-step explanation:
The cross section AFGD is a rectangle. Then, its area can be calculated with this formula:

Where:
"A" is the area of the rectangle.
"l" is the lenght of the rectangle.
"w" is the width of the rectangle.
Then, from the figure, you can identify that the dimensions of the rectangle AFGD are:

Therefore, you can substitute these values into the formula
to find the area of the cross section AFGD. Then, you get:

It would be 1000 since the 2 is not bug enough to carry it over.
Answer:
6. c. 120
7. $6.45
Step-by-step explanation:
1. 150 x 0.20 = 30
2. 150- 30= 120
1. 43 x 0.15= 6.45
Answer:
1. The like terms are 11x and 2x and the terms are 11x and 2x
2. The like terms are 9x and -5x and the terms are 9x and -5x
3. the like terms are (21x and x) and (6 and -5) and the terms are 21x, 6, -x, and -5.
4. The like terms are (8x and -3x) and (14 and 1). And the terms are 8x, 14, -3x, and 1.
