X/y = 4 , x = 4y
x^2 -12y^2 = (4y)^2 - 12y^2 = 16y^2 -12y^2 = 4y^2
The definition of math is the overall group of sciences that study numbers, shapes and their relationships. An example of math is arithmetic, the study of addition, subtraction, multiplication and division. ... (uncountable, North America) Arithmetic calculations; (see do the math).
The value of y would be 60
The way you would solve this is by plugging in 7 for x.
After you plug in the 7 for x you would have to multiply 7 by 4 to get 28.
Next you would add 28 to 32 to get 60.
Your final answer should be y=60
So basically you have to see how the person is built but in average it will took like 12minutes
