326=12m+6c+x The reason your x does not have a number is because it is unknown so in order to solve for x you need to get rid of the 12m+6c so in order to that you can divide it on both sides so you would get 326/12m+6c=x the divide your numbers 18.1=x but you cant have a tenth of a djembe drum so you would have to round up to 19.
The answer here is 13. 20 divided by 4 is 5 /‘d 2 to tbe third power is 8. It is 5+8 which is 13
Remark: What might be confusing you is the the given expression must add up to 90o. You know this because <B = 90 so the other two angles must be 90o.
Equation
5x - 10 + 6x - 21 = 90 Combine like terms on the left
11x - 31 = 90 Add 31 to both sides.
11x - 31 + 31 = 90 + 31
11x = 121 Divide by 11
x = 121/11 = 11.
Find the value of 6x - 21
6*11 - 21 = 66 - 21= 45
Comment
The central angle for arc AB (which is double ADB = 2*45 =90) is 90. So arc AB = 90
A. 36 is the correct answer

<em>Question was unclear! See below for answer possibilities!</em>
Step-by-step explanation:
<u>IF "-1" MEANS MULTIPLY BY NEGATIVE 1</u>
2((42) -1 ))
2(-42)
<h2><em>-84</em></h2>
<u>IF "-1" MEANS SUBTRACT 1</u>
2((42)-1)
2(41)
<h2>
<em>82</em></h2>
Hope this helps
