The answer for this problem is that x = 60°, or B.
We can solve this problem by using our knowledge of quadrilaterals. In this problem, we need to know that the number of degrees in a quadrilateral is equal to 360, but, the formula to find the number of degrees in a polygon with n sides is (n-2) * 180.
Now that we know that the sum of the angles if 360°, we can add all the angles and solve for x. The angles with the squares are 90°.
2x° + x° + 90° + 90° = 360°
Get x by itself, combine like terms.
3x° + 180° - 180° = 360° - 180°
3x° = 180°
x = 60°, or B.

ANSWER: Multiply and Divide from left to right
To do this question we must follow the rules of PEMDAS. The first step would be to evaluate the equation given to us in the parentheses. To solve that we would have to use PEMDAS once again which tells us to multiply 2 x 2 before we add 3, so we get 7. Now that there is no more Parentheses, our second step is to evaluate each Multiplication and Division expression from left to right. This would start by dividing 63 by 7 to get 9.
Answer:
1,235,520
Step-by-step explanation:
13P6 = 13!/(13-6)! = 13·12·11·10·9·8 = 1,235,520
__
There are 13 ways to choose the first object, 12 ways to choose the second, 11 ways to choose the third, and so on. The 6th object can be chosen 8 ways.
The total number of permutations is the product of all these ways:
13·12·11·10·9·8 = 1,235,520
