First off, let's take a look at what these numbers are:
Real numbers: It can be any numbers,both rational and irrational.
Natural numbers: The number has to be integer and positive.
Integers: A number without fraction or demical place.
Whole number: The number has to be natural and cannot be negative.
Therefore, as 12 is a positive number with no demical place or fraction, it is real numbers,integers, whole numbers, and natural numbers.
Hope it helps!
Answer: 60
Step-by-step explanation:
It’s an equilateral triangle based on the congruent sides.
Answer:
127.41
Step-by-step explanation:
side KJ equals 17 which corresponds to side NM which equals 57. These two triangles are similar which means the bigger triangle will be the smaller triangle but enlarged. So 57 divided by 17 equals 3.353 and then you do the same with the other side but multiplication; 38 times 3.353 equals 127.41. :)
Since this line is one single line you want to add the two parts rather than multiply.
(x - 7) + (x - 3) = 12
x - 7 + x - 3 = 12
Next you want to simplify everything so add the values with the variables together and add the constants together
2x - 10 = 12
Get the term with the variable on one side
2x = 22
Divide by 2 on both sides to find x
x = 11
