Answer:
The answer is 32.
Step-by-step explanation:
Remember that order of operation is very important in this problem.
Substitute x for 3 and y for 2 in the equation.
When solving the first term, we must note that we have to square the 3 first before we multiply it by 4. So, 4(3)^2 is basically 36. To simplify the second term you just have to do 2*2, which is 4. 36-4=32, which is the answer.

Answer:
BC=3root7
CD=root58
Step-by-step explanation:
According to Pythagorean theorem, in a right triangle,a^2+b^2=c^2. a, b are two legs of right triangle. Cis the hypotenuse
12^2-9^2=63
BC=root63=3root7
BD^2-BC^2=CD^2
121-63=CD^2
CD=root58
