Which expressions are equivalent? select equivalent or not equivalent for each pair of expression.

First one:
Not equivalent, because 3 is also being multiplied with b, since 3 is being multiplied against a and b.
So therefore, to be equal, it must be 3a + 3b.

Second One:
Yes, it is equal, because 4 is being distributed to everything, 2y * 4 -> 8y and 4 * x-> 4x

I hope this sorta helped!

Volume of Cylinder =

Volume of container A= cubic in.

Cost of container A=137.135x0.03=$4.12.

Volume of container B= Base area x height=12.57x10=125.7 cubic in.

Cost of container B=125.7x0.03=$3.77

Volume of container c= cubic in

Cost of container C= 276.32x0.03=$8.29.

Volume of container D= cubic in.

Cost of container D=169.56x0.03=$5.08.

Given The company does not want the new container to cost more than $4.00 to fill.
