Answer:
(2x - 3)(x - 2).
Step-by-step explanation:
Factor: 2x^2 - 7x + 6
Use the ac method to do this:
Multiply the leading coefficient by the last term:
2 * 6 = 12.
Now we want 2 numbers whose product is 12 and whose sum is -7.
That would be -3 and -4 so we write:
2x^2 -4x - 3x + 6
Now factor by grouping:
= 2x(x - 2) - 3(x -2)
(x - 2) is common to the 2 parts so we have:
(2x - 3)(x- 2).
Box A is the plot that represents the data set hope this helps:)
Answer: l=3
w=5
b1=4
b 2=1
h=5
l=3
w=3
Step-by-step explanation: hope this helps
Let y represent the number of feet and x represent the number of minutes. Convert 22 1/2 to decimal form: 22.5
y = -22.5x
Plug in -315 for y
-315 = -22.5x
divide both sides by -22.5
14 = x
It will take 14 minutes.
The area of regular polygon with 5 sides is 689.65m²
<u>Explanation:</u>
All sides of a regular polygon are equal in length. If you know the length of one of the sides, the area is given by the formula:
![area = \frac{s^2n}{4 tan(\frac{180}{n}) }](https://tex.z-dn.net/?f=area%20%3D%20%5Cfrac%7Bs%5E2n%7D%7B4%20tan%28%5Cfrac%7B180%7D%7Bn%7D%29%20%7D)
where
s is the length of any side
n is the number of sides
tan is the tangent function calculated in degrees
Let the number of side of a polygon be 5. So, putting the values in equation
![area = \frac{(20)^2X5}{4 tan(\frac{180}{5}) } \\\\ = \frac{2000}{2.9} \\\\= 689.65 m^2](https://tex.z-dn.net/?f=area%20%3D%20%5Cfrac%7B%2820%29%5E2X5%7D%7B4%20tan%28%5Cfrac%7B180%7D%7B5%7D%29%20%7D%20%5C%5C%5C%5C%20%3D%20%5Cfrac%7B2000%7D%7B2.9%7D%20%5C%5C%5C%5C%3D%20689.65%20m%5E2)
Therefore, the area of regular polygon with 5 sides is 689.65m²
