A scalene triangle can never be an isosceles triangle. How? Well, let's take a look at the definition of a scalene triangle. In short, a scalene triangle is a classification of a triangle that does not have any congruent sides. On the other hand, an isosceles triangle is a triangle in which its legs are both congruent. Therefore, if a scalene triangle has two congruent legs, it wouldn't even be a scalene triangle, but instead it would be an isosceles triangle.

Answer:
7.4 · 10^4
Step-by-step explanation:
For scientific notation, multiplication is pretty simple. 
In this case, you would only multiply the "regular" number by 2.
(3.7 · 2) · 10^4
= 7.4 · 10^4
However, if it were asking about multiplying the number with something else in scientific notation, in addition to what we did above, you'd add together the exponents. 
I hope this helped!
