Answer:
the answer would be c
Step-by-step explanation: Because the values inside of the parenthesis don't have the same variable, they cannot be combined. Using the 9 on the outside of the parenthesis you would multiply 9 by 3r, which gives you 27r, and 9 by -4 to create -36. The new equation would be 27r - 36, which is equivalent to the equation shown next to it.

Answer:
<h2>49.49%</h2>
Step-by-step explanation:
volume of liquid in the flask= 200 cm^3
radius of the flask = 3 cm
height of the flask= 12 cm
volume of flask is given by =
putting values and solving we get =396 cm^3
therefore the volume unfilled= 396-200= 196cm^3
therefore % of volume unfilled= 196/396*100= 49.49%
