Answer:
see below
Step-by-step explanation:
A: 2x² - 3x - 5
(2x - 5)(x + 1)
B: Set the factored equation equal to zero and solve for x.
(2x - 5)(x + 1) = 0
2x - 5 = 0
2x = 5
x = 5/2
x + 1 = 0
x = -1
The x-intercepts are 5/2 and -1
C) To find the end behavior, you need to look at the term in the unfactored equation with the highest exponential number. For this equation, that is 2x². Since the exponent is positive, both ends of the graph will point in the same direction. Because the leading coefficent is positive, the graph will point upwards. The end behavior of the graph is that as the x-values approach both ∞ and -∞, the function approaches ∞.
D) Since we know that the x-intercepts are 5/2 and -1, you can plot these points. You also know that the graph will be in an upward U shape. Plug in a couple x-values and plot them to make the graphing of the equation more accurate.
Answer:
area = 84 m²
Step-by-step explanation:
area = (1/2)(4)(3)(2) + (5)(6) + (6)(3) + (4)(6) = 84 m²

<u>The only function with mentioned parameters is:</u>
Correct option is A
<u>The other options don't fit:</u>
- B. Even degree with negative leading coefficient
- C. Odd degree
- D. Odd degree
Answer:
x-5
Step-by-step explanation:
So glad I could help! Here's why well we do definitely need to factor the area.
Because when factoring we have to expressions multiplying by each other.
A=LxW
Factored Expression=(x+5)(x-5)
See now it's LxW.

There needs to be a picture of the whole worksheet for me to answer. But you can go to the website at the bottom of the sheet and most likely find a answer key.
