Answer:

13.5x + 5

Step-by-step explanation:

12x + 1.5x - 2 - 7 (you always want to work left to right)

13.5x - (2 - 7) (you are free to use the associative property here to isolate like terms)

13.5x - (-5) (remember a number less in value subtracted from a higher value will result in a negative value; giving you this value for instance.)

13.5x + 5 (now since it was basically subtracting a negative from 13.5x you can technically say the same thing by turning the negative value to a positive however you must do the opposite of subtraction as well.)

10.5x-9 is correct but I think there may be an equal sign in this question if not this is right

Answer:

B. A rectangle, 4 in by 3 in

Step-by-step explanation:

The foam has the shape of a cuboid with base of 10 in by 4 in and height of 3 in.

The foam has a front elevation of a rectangle with dimension of 4 in by 3 in. It has a left elevation of dimension 10 in by 3 in and a plan of dimension 10 in by 4 in.

If the foam is cut along the red line, the exposed face would be the same as the shape of the front elevation. Hence the shape of the cross section would be a rectangle with dimension of 4 in by 3 in.
