Answer:
Step-by-step explanation:
The parabola's are
So
So, the points at which the parabola's intersect each other is 
and 
The three points of the triangle are , and 
Area of a triangle is given by
![A=\dfrac{1}{2}[x_1(y_2-y_3) + x_2(y_3-y_1) + x_3(y_1-y_2)]\\\Rightarrow A=\dfrac{1}{2}[2(5-0)+(-2)(0-5)+0(5-5)]\\\Rightarrow A=10\ \text{sq. units}](https://tex.z-dn.net/?f=A%3D%5Cdfrac%7B1%7D%7B2%7D%5Bx_1%28y_2-y_3%29%20%2B%20x_2%28y_3-y_1%29%20%2B%20x_3%28y_1-y_2%29%5D%5C%5C%5CRightarrow%20A%3D%5Cdfrac%7B1%7D%7B2%7D%5B2%285-0%29%2B%28-2%29%280-5%29%2B0%285-5%29%5D%5C%5C%5CRightarrow%20A%3D10%5C%20%5Ctext%7Bsq.%20units%7D)

You need to add two mixed numerals.
One is positive and one is negative.
To add a positive number and a negative number, first take the absolute value of both, making them both positive. Then subtract the smaller absolute value from the larger absolute value. Finally, the sign of the answer is the same sign as the number that has the larger absolute value.
The numbers are -4 5/8 and 2 1/8
Take absolute values:
|-4 5/8| = 4 5/8
|2 1/8| = 2 1/8
Subtract the smaller absolute value from the larger absolute value.
4 5/8 - 2 1/8 = 2 4/8 = 2 1/2
The greater absolute value is 4 5/8.
Since the number with the larger absolute value was -4 5/8, a negative number, the answer is negative, -2 1/2
-4 5/8 + 2 1/8 = - 2 1/2
I'm assuming that the number after the variable is supposed to be the exponent.
Combine like terms to get:
