Answer:
Molly
Step-by-step explanation:
Brady did not properly create a square.
The square of a binomial is ...
(a -b)² = a² -2ab +b²
Where a²=x² and -2ab = -4x, you find b=2. The constant term in the square is 2²=4. Brady shows it as -4, which is incorrect.
Molly's work is correct.
Answer:
r = 32
Step-by-step explanation:
R is the variable that we are trying to find.
24 = 3/4r
Since r is being multiplied by 3/4, we need to divide 3/4 on both sides to "undo" the multiplication.
24 / 3/4 = 3/4r / 3/4
32 = r
Therefore, r = 32.
To check, we can plug 32 into the equation.
24 = 3/4 x 32
3/4 x 32 = 24
A. it has a volume of 1 cubic unit
