Answer:
The answer is given below
Step-by-step explanation:
A) Integers are whole numbers (without fraction) that are either positive or negative. If T={x:X is an integer between 1 and 4}, therefore the elements in set T = {2, 3}
B) Since the elements in set T = {2, 3}, then the number of elements in set T = 2
C) The subsets of set T are {}, {2}, {3} and {2,3}
D) Proper subset of set T are subsets of T that is not equal to T. The proper subsets of T are {2} and {3}
An improper subset of set T contains all the element of set T and a null element. The improper subset of set T are {2,3} and {}

You cannot take the square root of a negative number and get a real number answer. You can only get an imaginary root.
square root of 49 = 7 and square root of 64 = 8
square root of 61 is between 7 and 8.
It would be closer to 8.
square root of -49 = 7i and square root of -64 = 8i
square root of -61 would be closer to 8i
Answer:
Step-by-step explanation:
We can set up the following equation:
where 
is the total number of shapes on Abigail's paper.
Let's first multiply both sides by :
Next, let's multiply both sides by 
:
Finally, let's divide both sides by 
:
Answer:
108 one-bedroom units
72 two-bedroom units
36 three-bedroom units
Step-by-step explanation:
<em>Let x, y, z the number of one-bedroom, two-bedroom and three-bedroom units respectively.</em> Then
1) x+y+z = 216
2) y+z = x
3) x = 3z
Multiplying equation 1) by -1 and adding it to 2), we get
-x = x-216 so, x = 216/2 = 108
x = 108
Replacing this value in 3) we get
z = 108/3 = 36
z = 36
Replacing now in 2)
y+36 = 108, y = 108-36 and
y = 72
