7.9168 x 10^8
790000000 + 1680000 = 791680000
The right triangle is also Isosceles. It has two equal angles of 45°.
(hypotenuse)² = 2S²
4 = 2S² => S = √2
Therefore B is the correct answer.
Isolate k by dividing both sides by 8
8k=4/9
k=4/72
Reduce if possible
4/72 -> 1/18
Its c because first 14 he got -42 the four remaining he got 8=-34
