We got to add these together so
2x^2-8x-9+3x^2+8x-2
the 2x^2 and 3x^2 add to 5x^2
the 8x and -8x cancel each other out
the -9 and -2 add to -11
so..
5x^2 - 11

Which of the boxplots a b or c shows a sample that has range 21, interquartile range 11, median 14
Answer:
A
Step-by-step explanation:
Range = max value - min value = 21
Box plot A has a max of 26 and a min of 5
Range of box plot A = 26 - 5 = 21
✔️Box plot A has a range of 21
Interquartile range = Q3 - Q1
Q3 of Box plot A = 20
Q1 of Box plot A = 9
✔️Interquartile Range of Box plot A = 20 - 9 = 11
✔️Range of Box plot A is the value at the vertical line that divides the box = 14.

POPULATION In 2000, the world population was calculated to be 6,071,675,206. The world population increases at a rate of about 1.2% annually.
Write a function that represents the world population y after x years.
A) y = 6,071,675,205(1.012)^x
B) y = 6,071,675,206(1.012)^x
C) y = 6,071,605,205(1.012)^x
D) y = 6,071,675,215(1.012)^x
PLEASE HELP!!
Answer:
B) y = 6,071,675,206(1.012)^x
Step-by-step explanation:
It appears that this question asks for an exponential model that represents the population growth. I believe you could view the equation in the form y = (initial population)(rate)^x
Since the initial population is 6,071,675,206, you could substitute that in to get y = 6,071,675,206(rate)^x
Since your rate is increasing by 1.2% (0.012 in decimal form), just convert that to decimal form (knowing that 100% = 1.0, add 0.012 to get 1.012). Substitute that in to get y = 6,071,675,206(1.012)^x
Hope that helps. Feel free to let me know if it made sense.

The length of a rectangle is three times its width.
If the area of the rectangle is 75 ft?, find its perimeter
Answer:
I think the answer is 40.
Step-by-step explanation:
Since the length is three times its width, the width is 5 and the length is 15, since you find the area by doing length * width you get 75. You get perimeter by adding all the sides which is, 5+5+15+15= 40.

what is the slope of the line that passes through the points (3,-2) and (9,-2)? 0 3 -3 undefined
Answer:
[tex]\boxed{\textsf{ The slope of the line is $\bf{\dfrac{3}{2}}$.}}[/tex]
Step-by-step explanation:
Two points are given to us and we need to find the slope of the line that passes through these two points . The two points are (3,-2) and (9,-2) .As we know that the slope of the line is given by [tex]\tan\theta[/tex]
Slope of a line is :-
[tex]\qquad\boxed{\boxed{ \sf Slope =\dfrac{ y_2-y_1}{x_2-x_1}=\tan\theta }}[/tex]
On using this formula we can find the slope of the line .
Putting the respective values :-
[tex]\sf\implies Slope = \dfrac{y_2-y_1}{x_2-x_1}\\\\\sf\implies Slope = \dfrac{ 9-3}{2+2} \\\\\sf\implies Slope =\dfrac{6}{4}\\\\\sf\implies\boxed{\pink{\sf Slope = \dfrac{3}{2} }}[/tex]
