Answer:
9
Step-by-step explanation:
Answer:
In other words: any of the prime numbers that can be multiplied to give the original number. ... Example: The prime factors of 15 are 3 and 5 (because 3×5=15, and 3 and 5 are prime numbers).
Answer:
And we can subtract 4x in both sides and we got:
Now we can subtract in both sides 16 and we got:
And if we divide both sides by 4 we got:
And the best solution would be:
-7
Step-by-step explanation:
For this case we assume the following equation:
And we can subtract 4x in both sides and we got:
Now we can subtract in both sides 16 and we got:
And if we divide both sides by 4 we got:
And the best solution would be:
-7
We use 2 different rules here:
1) sum of angles in a triangle is equal to 180 degrees
2) when a triangle side is a diameter of the circle, then angle opposite to diameter is equal to 90 degrees.
so from 2) we know that B= 90
then from first one:
sum of angles = 180 = 90 + (3x + 6) + x = 96 + 4x
so 180 - 96 = 4x
so x = 84/4
x = 21
so answer is
A= 3x+ 6 = 63 + 6 = 69
B = 90
C = 21
