Answer:
P = 2n + 8m - 1
Step-by-step explanation:
A <u>trinomial is an expression or equation that has three terms</u>. A term is when between the numbers or variables, the operations are neither subtraction nor addition, or when there is only one number.
If two terms have the <u>same variable</u>, called <u>like terms</u>, they can be combined by addition or subtraction.
The perimeter is the total length of all the sides.
The formula for the perimeter of a triangle is for each of the three sides.
Substitute each of the three sides.
brackets can be removed
rearrange equation according to like terms
collected the like terms by addition
Answer:
Option D is the correct choice.
Step-by-step explanation:
We have been given a data set representing the total number of pencils each student in a class needs to sharpen as:
0, 1, 1, 1, 2, 3, 4, 4, 6, 6, 9
Let us find median of our given data set. As our data set has 11 data points, so median will be the value of 6th data point, that is 3.
Since first quartile is the median of the lower half of the data. Let us find our lower quartile. Since there are 5 data points below median, so our lower quartile will be the value of 3rd data point, that is 1.
Upper or 3rd quartile is the median of the upper half of the data. Since there are 5 data points above median, so our upper quartile will be the value of 9th data point, that is 6.
We can see that box plot represented by option D is the correct choice as middle line of box is at 3, which represents median of our data set. Lower quartile is at 1 and upper quartile is at 6.
Therefore, box plot shown in option D correctly represents the data.
Answer:
C
Step-by-step explanation:
If you look at the two angles, one is 7x and the other is 11x, they appear to be next to each other and make a right angle, if you look at the bottom corner of them there is a square which means it is a right angle. this means that if you put 7x with 11x it would = 90
I beleive it is A or B if I had to choose I'd go with A
Answer:
To move from (a, b) to (a, -b) move down 2b. The point (a, -b) would be in quadrant 4 and would be a reflection across the x-axis of the point (a, b)
