Answer:
7 is the prime factor that is common to all three numbers.
7x5 = 35
7x12 = 84
7x3 = 21
Let me know if this helps!
Answer: The set of integers is closed for addition, subtraction, and multiplication but not for division.
I'll solve 21, and you then should be able to solve the rest on your own!
Since ADC is 135, that means that that whole angle is 135 degrees. In addition, since angles ADB and BDC add up to ADC, we get ADB+BDC=ADC=135=11x+9+7x=18x+9. Subtracting 9 from both sides, we get 126=18x. Dividing both sides by 18, we get x=7. Plugging that into 11x+9=BDC, we get 11*7+9=77+9=86
Answer:
14.2825569 or 14.28
Step-by-step explanation:
Use the pythagorean theorem, put 20 in as c and 14 as b, then solve
20^2-14^2=a^2
400-196=204
square root of 204= 14.2825569
