You must use distributive property to get 2m+10+48m+8 and then add all like terms. You get 50m+18 as your final answer.
Tbh i’m just trying to get points
The general pattern that these diamonds follow is that the top number is the result of multiplying the numbers in the middle; while the bottom number results from adding these numbers. This pattern can be used to find the numbers in the fourth diamond. Moreover, the numbers that complete the diamonds are A (15,8), B (2,-3), C (4,2), D(4,8.5), E (-3.-4)
<h3>What is the general pattern in the diamonds?</h3>
Based on observation, you can determine in these diamonds the top number is obtained by multiplying the numbers in the middle, while the bottom number is obtained by adding these numbers.
<h3>What numbers complete the diamonds?</h3>
Diamond A
Top number: 15 (3x5)
Bottom number: 8 (3+5)
Diamond B
Top number: 2 (-2x-1)
Bottom number: -3(-2+-1)
Diamond C
4, 2 because 4x2 = 8 and 4+2 = 6
Diamond D
Top number: 4( 8x0.5)
Bottom number: 8.5(8+0.5)
Diamond E
-3,-4 because -3x-4= 12, and -3+-4= -7

Answer: Approximately 13 square units (choice B)</h3>
===========================================================
Explanation:
The given reflex angle is 215 degrees. A reflex angle is anything over 180 degrees, but less than 360. Subtract 215 from 360 to get the measure of angle AOB
angle AOB = 360 - 215 = 145
angle AOB = 145 degrees
We'll use this later.
Now find the area of the full circle. Use the formula A = pi*r^2. The radius is r = sqrt(10) which can be found through the distance formula or the pythagorean theorem. You want to find the length of either OA or OB to get the radius.
The area of the circle is
A = pi*r^2
A = pi*(sqrt(10))^2
A = 10pi
This is the exact area of the full circle, but we want just a fractional portion of it. Specifically we want the pie slice that is formed by angle AOB
area of sector AOB = [ (angle AOB)/360 ] * (area of full circle)
area of sector AOB = (145/360)*10pi
area of sector AOB = 145pi/36
area of sector AOB = 145*3.14/36
area of sector AOB = 12.647 approximately
area of sector AOB = 13 square units approximately, after rounding to the nearest whole number
