The answer is 5
Because if x = 2 then you just do 2+3 which is 5
Answer:
Correct choices are 1 and 4
Step-by-step explanation:
As per data given we have:
- Median temperature is 75°F and 88°F
- And the range from the median is 5° for both cities
This gives us lowest temperatures of:
- 75° -5° = 70° and 88° - 5°= 83° respectively
And high temperatures are:
- 75° + 5° = 80° and 88° + 5° = 93°
<u>Answer choices based on above details:</u>
- Choice 1 - correct
- Choice 2 - incorrect. Correct answer is 93°
- Choice 3 - incorrect. Correct answer is 93° - 70° = 23°
- Choice 4 - correct
Let's take l and w as the length and the width of the rectangle.
According to the given information the length is 3 less than twice the width:
And the area, which is the product of the length times the width is 14. Using the equation above, we can re write the formula for the area, this way:
Now, we have to solve the quadratic equation using the quadratic formula:
w has 2 values, but for this context, the logic value is 7/2. It means that the width of the rectangle is 7/2.
Now, we can use this value and the first equation to find the length:
The length of the rectangle is 4 and the width is 7/2.
The domain of the graph is [-3, 2) and the range is (-4, 5]
<h3>How to determine the domain and the range?</h3>
From the given graph, we have the following highlights:
- Minimum x value = -3 (closed circle)
- Maximum x value = 2 (open circle)
- Minimum y value = -4 (open circle)
- Maximum y value = 5 (closed circle)
Open circles are represented with () while closed circles are represented with []
Hence, the domain of the graph is [-3, 2) and the range is (-4, 5]

Answer:
(2x - 3a³) ,(2x + 3a³)
Step-by-step explanation:
Given that
4x^2-9a^6
As we know that
x² - y² = ( x+y)(x-y)
So
4x^2-9a^6 = (2x)² - (3a³)²
By using the above formula
x² - y² = ( x+y)(x-y)
4x^2-9a^6 = (2x)² - (3a³)²
4x^2-9a^6 = (2x - 3a³) (2x + 3a³)
So the factor is (2x - 3a³) ,(2x + 3a³)
To verify
Multiple both factors
(2x - 3a³) (2x + 3a³) = 2x .2x -2x . 3a³ + 3a³ . 2x - 3a³. 3a³
=4x² - 9 a ⁶
