Answer:
Step-by-step explanation:
Three times a number x : 3x
Three times a number x increase by 4: 3x +4
Five times the number x: 5x
5x = 3x +4
Subtract 3x from both the sides.
5x - 3x = 3x +4 - 3x
2x = 4
Divide both sides by 2
2x/2 = 4/2
x=2
The number is 2
Answer:

Step-by-step explanation:
It’s 3 points or more which lie in the same plane
Answer:
Step-by-step explanation:
This is where knowing the exponent rules come into play. The negative exponent applies for both 6 and 2.
The negative exponent rule is basically reciprocal of x. So, if x is the numerator, it gets moved to the denominator, and vise versa. Also, the power of a power applies here too with the implied 1st power.
Option 2: ∠K, ∠L is the correct answer
Step-by-step explanation:
In triangles, the relationship between angles and sides is as follows
- The side in opposite to the largest angle in triangle is the largest.
- The side opposite to smallest angle in triangle is the smallest.
In the given triangle the longest side is 10 so the angle in front of this side ∠K will be the largest.
The smallest side is 6 so the angle opposite to it ∠L will be the smallest.
Hence,
Option 2: ∠K, ∠L is the correct answer
