I think the correct answer is b 75
c.
Higher education can be expensive, and most students who seek degrees must accept some burden of debt.
Rectangle.
Explanation: Rectangles have four interior angles, all of which are right angles measuring 90 degrees each.
We have the expression

We can already simplify x because it's both on the numerator and denominator

Now we can simplify 425/25 = 17

Remember that

Then

The final result is
We can solve this in many ways, let's try this one.
T∧2 = 4 pi∧2 * a∧3 / GM First we will multiply whole equation with variable( or parameter) M and get
M * T∧2 = 4 pi∧2 * a∧3 / G After that we will divide whole equation with variable ( or parameter ) T∧2 and get
M = 4 pi∧2 * a∧3 / G * T∧2
This is correct answer
Good luck!!!
