Answer:
Step-by-step explanation:
Begin by filling in x as -2 and y as √12 in the given expression:
. Work inside the parenthesis first and deal with those exponents:
(-2)³ is the same as (-2)(-2)(-2) which is -8;
(√12)² is the same as (√12)(√12) which is √144 which is 12.
Filling those simplifications in:
To find out the missing leg of a right triangle, you have to use the Pythagorean Theorem which is a^2 + b^2 = c^2. C is the hypotenuse. So, substitute the numbers into that equation.
2^2 + 4^2 = x
4 + 16 = x
20 =
The answer is A because when you add the angles to get they equal 180. Then just solve for x.
