I’m not exactly sure how to calculate the grade, but this is what I’ve done below. Hope it helps!
The answer is B
volume of rectangular prism = (area* height )
so 2 * 4 * 9 = 72 cm3
9* 4 * 2 = 72 cm3
but they have differant surface area
Answer:
The answer is 0.2. It is an irrational number with a repeating 2. It should have a line over the two to represent it repeating.
Step-by-step explanation:
First divide 2 by 9.
Use a calculator or do it by hand.
You get your answer.
using the LCD method.... well, there are a couple of ways, but let's simply add them up.
well, the denominators are 5x and 2x... so the only LCD will just be 10x, since it's divisible by both, so let's use that one.

All of them have the same answer of -8 except the last one.
