Answer
46.24
Explanation
n² = n × n
∴ (-6.8)² = (-6.8) × (-6.8)
= 46.24
The answer is positive since (-1)×(-1) = 1.
-6.8^2
You can do this with a calculator or pen and paper.
With a calculator;
-6.8 squared = 46.24 (Notice that the answer is positive!)

The value of x is 7 cm, as it's a 45-45-90 triangle, also known as an isosceles right triangle, where sides opposite the 45° angles are equal in length.
In this case, we're dealing with a 45° angle, which is part of a 45-45-90 special triangle, often referred to as an isosceles right triangle.
We know that in a 45-45-90 triangle, the sides are in the ratio of 1:1:√2.
Knowing this, we can easily find the length of the unknown side (BC), which we dubbed as 'x'.
In a triangle with a 45° angle and hypotenuse of 7 cm (side AC), the length of the other side (BC) would be the same as the side adjacent to the 45° angle because it is an isosceles triangle.
Therefore, 'x' in this instance is also 7 cm.

A trapezoid is a quadrilateral containing at least one or two parallel sides. Since the other two sides of these figures were parallel, these fulfill not only the trapezoid requirements, as well as the trapezoid requirements.
Therefore, the answer is "Last choice."
