Triangle: 13.3 km Why: the formula is 1/2 base x height.
Square: 57.4 Why: 7x8.2 which equals 57.4
The zeros of a function are the values of x that make the function be equal to zero.
When graphing a quadratic equation, the graph is a parabola, and the zeros of the function are the x-intercepts of the graph, which are the points where the graph intersects the x-axis.
So, if the zeros of this function are x = -8 and x = 2, that means the parabola crosses the x-axis at x = -8 and x = 2.
Therefore the correct option is the first one.
-15 is already rational itself, but it as a fraction:
-15/1
Answer:a right angle
Step-by-step explanation: The rectangle has right angles. When the angles are diagonals the angles are bisected therefore what was 90 is now 90/2=45. A triangle of any kind should equal 180 so lets check it 90+45+45=180.
