Answer:

18.9c - 11.2d + 9.3f

Step-by-step explanation:

<u>First, write the equation as adding all the parentheses together like so:</u>

(9.7c - 1.9d) + (9.2c + 1.1f) + (8.2f - 9.3d)

<u>Remove the parentheses:</u>

9.7c - 1.9d + 9.2c + 1.1f + 8.2f - 9.3d

<u>Collect like terms (9.7c and + 9.2c):</u>

18.9c - 1.9d + 1.1f + 8.2f - 9.3d

<u>Collect like terms again (1.9d and - 9.3d):</u>

18.9c - 11.2d + 1.1f + 8.2f

<u>Collect like terms again (1.1f + 8.2f)</u>

18.9c - 11.2d + 9.3f

Can someone plz help me
Illusion [34]
First rectangle:
Has 3 cubes in each 5 layers, and imagine it, so we have all dimension needed which is:
l=3 unit
w=1 unit
h=5 unit.
V=l×w×h
V=3×1×5
V=15 cubic inches.

Second rectangular:
Doing the same like that to get:
l=5 unit
w=1 unit
h=3 unit
V=15 cubic inches. As a result, there are no prism that are greater to each other, which mean that they have the same volume of 15 cubic inches. Hope it help!
