Answer:
440 square inches.
Explanation:
We can consider the boxes as one single shape.
So it's base area is 12×10=120 and the area of the side faces is 20×12=240 and 20×10=200.
Now, there are 2 of each, so let's add up everything and multiply by 2.
(120+240+200)×3=560 square inches.
But we have to take off the base, so:
560-120=440 square inches
Answer:
B. y = x - 2
Step-by-step explanation:
The sale price (y) is $2 less than the original price (x - 2).
To test this out, if a book's original price is $10..
x = 10
Using y = x - 2 and to test out if it works, we'll plug in x = 10 to discover y.
y = 10 - 2
y = 8
