Hey there! :)
Answer:
29/28.
Step-by-step explanation:
Starting with:
![\frac{1}{4} + \frac{2}{7} + \frac{1}{2} =](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B4%7D%20%2B%20%5Cfrac%7B2%7D%7B7%7D%20%2B%20%5Cfrac%7B1%7D%7B2%7D%20%3D)
Begin by finding a common denominator. A number that contains all of the denominators as a factor would be 28. Change each fraction to contain a denominator of 28:
![\frac{7}{28} + \frac{8}{28} + \frac{14}{28} =](https://tex.z-dn.net/?f=%5Cfrac%7B7%7D%7B28%7D%20%2B%20%5Cfrac%7B8%7D%7B28%7D%20%2B%20%5Cfrac%7B14%7D%7B28%7D%20%3D)
Add the fractions:
![\frac{7}{28} + \frac{8}{28} + \frac{14}{28} = \frac{29}{28}](https://tex.z-dn.net/?f=%5Cfrac%7B7%7D%7B28%7D%20%2B%20%5Cfrac%7B8%7D%7B28%7D%20%2B%20%5Cfrac%7B14%7D%7B28%7D%20%3D%20%5Cfrac%7B29%7D%7B28%7D)
Therefore, the fractions sum up to 29/28.
So first off, remember the formula for the area of a rectangle. it's length time width right? or, you could think that A= 2 things multiplied together. how can we simplify x^2 - x -72 to equal two things multiplied together? well, we can factor it! We know that one of the factors is x+8 right? so what's the other factor? it would be x-9. so, we know width is x-9. I'm not sure if you need an actual value for width. if so, I could probably go further.
No because there is no picture and circles
Answer:
C
Step-by-step explanation:
The secant- tangent angle MLK is half the difference of the intercepted arcs, that is
(KN - KM) = 70° ( multiply both sides by 2 to clear the fraction )
KN - KM = 140°
KN - 61° = 140° ( add 61° to both sides )
KN = 201° → C
Subtract 5 from both sides
a/-8 = 4/7 - 5
simplify 4/7 - 5 to 31/-7
a/-8 = 31/-7
multiply both sides by 8
-a = 31/-7 x 8
simplify 31/7 x 8 to 248/7
-a = 248/7
multiply both sides by -1.
The answer is a = 248/7
