Answer:
Alexander is incorrect because the expressions are not equivalent.
Step-by-step explanation:
If the expression is evaluated for any value of x, y; the result will not be same.
For instance, let assume x = 1 and y = 2
3x + 4y = 3 + 4 = 7
(3)(4) + xy = (3)(4) + (1 * 2) = 12 + 2 = 14
So, the expressions are not the same and Alexander is incorrect.
I would assume it would be dividing both sides by three although if someone were to actually solve this I would say multiply 2 and 3 together first.
Hope this helps :)

(3) (z+2)
(3) (z)+(3) (2)
3z+6
Answer:
240/r = h
Step-by-step explanation:
480π = πr2h Write out the equation
480 = r2h Cancel out π on both sides
240 = rh Divide by 2 on both sides
240/r = h Divide by r to isolate h and get your answer
