Using the combination formula, it is found that the integers can be chosen in 870 ways.
<h3>What is the combination formula?</h3>
is the number of different combinations of x objects from a set of n elements, given by:
The resulting sum will be even if both numbers are even(2 from a set of 30) or if both numbers are odd(also 2 from a set of 30), hence:
The integers can be chosen in 870 ways.

Answer:
C. (2x + 16) + (x) = 180°
Step-by-step explanation:
See attachment for the cyclic quadrilateral
One theorem of cyclic quadrilateral states that; opposite angles = 180°
In the attachment, the angle opposite B is D
Where B = x
D = 2x + 16
From the theorem stated above;
B + D = 180°
Substitute the values of B and D in the formula above
x + 2x + 16 = 180
From the list of given options, the correct answer is C
7^6 = 117,649
7 x 7 x 7 x 7 x 7 x 7 = 117,649
So, closest area to 7857.14 is 7854 square centimetres
