F(x) = 2x² + 7x - 5
g(x) = -8x² - 3x + 5
g(x) + f(x)
-8x² - 3x + 5 + 2x² + 7x - 5
-8x² + 2x² - 3x + 7x + 5 - 5
-6x² + 4x + 0
-2x(3x - 2)
Answer:

Step-by-step explanation:
The vertex form of a parabola:

(h, k) - vertex
We have the vertex at (3, 2) → h = 3 and k = 2.
Substitute:

The point (4, 6) is on athe parabola. Put the coordinates of this point to the equation:
<em>subtract 2 from both sides</em>


Finally:
<em>vertex form</em>
<em>use (a - b)² = a² - 2ab + b²</em>
<em>use the distributive property</em>

<em>standard form</em>
Answer:
3 by 2
Step-by-step explanation:
3+2+3+2=10
3*2=6

Ans: Option A.
Answer:
The area is 155 ft.
Step-by-step explanation:
To find the area if a trapezoid, you have to add the number on top( in this case 13 ft) and then add that with the bottom number(18 ft.) Then, you take that answer and divide it by 2. After that, multiply it with the height(10.) Thus, the answer is 155 ft.
