Answer:
A. X∪Y = {25, 36, 49}
B. X∩Y = ∅ i.e empty set
C. X' = {21, 22, 23, 24, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48}
D. X′∩Y∩Z = ∅
Step-by-step explanation:
We'll begin by determining the universal set (ε), set X, set Y and set Z.
This can be obtained as follow:
ε = {whole numbers less than 50 but greater than 20}
ε = {21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49}
X = {perfect squares}
X = {25, 36, 49}
Y = {factors of 12}
Y = ∅ i.e empty
Z = {prime numbers}
Z = {23, 29, 31, 37, 41, 43, 47}
A. Determination of X∪Y
X = {25, 36, 49}
Y = ∅
X∪Y =?
X∪Y => combination of elements in set X and Y without repeating any element in both X and Y.
X∪Y = {25, 36, 49}
B. Determination of X∩Y
X = {25, 36, 49}
Y = ∅
X∩Y =?
X∩Y => elements common to both set X and Y
X∩Y = ∅ i.e empty
C. Determination of X′
ε = {21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49}
X = {25, 36, 49}
X' =?
X' => elements in the universal set but not found in set X.
X' = {21, 22, 23, 24, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48}
D. Determination of X′∩Y∩Z
X' = {21, 22, 23, 24, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48}
Y = ∅
Z = {23, 29, 31, 37, 41, 43, 47}
X′∩Y∩Z =?
X′∩Y∩Z => elements common to set X', Y and Z
X′∩Y∩Z = ∅

the area of the rectangle shown represents a polynomial. the dimensions of this rectangle represent the ____
A. terms of the polynomial
B. square of the polynomial
C. product of the polynomial
D. factors of the polynomial
HELP ME BESTIES PLS
Answer:
D) Factors of the polynomial
Step-by-step explanation:
Example: If the polynomial 10x² represents the area of the rectangle, then
2x and 5x will be the dimensions of the rectangle. Thus they will be factors of the polynomial.
So, dimensions of the rectangle represents the factors of the polynomial.

Answer:
486√3 ft² ≈ 841.8 ft²
Step-by-step explanation:
The area of a regular hexagon with side length s is ...
A = (3√3)/2s²
For the side length of 18 ft, the area is ...
A = (3√3)/2(18 ft)² = 486√3 ft² ≈ 841.8 ft²
Emily walked around 2 parks. One measures 54 feet by 38 feet and other measure 32 feet by 22 feet. How much did she walk?
Answer:
292 feet
Step-by-step explanation:
If Emily walked round the two rectangular parks, she walked round the perimeter of the parks.
the total distance she walked can be determined by calculating the perimeter of each of the park and adding the perimeters together
Perimeter of a rectangle = 2 x ( length + breadth)
Perimeter of the first park = 2 x (54 ft + 38 ft) = 184 ft
Perimeter of the second park = 2x (32 + 22) = 108 ft
Sum of the perimeters = 184 ft + 108 ft = 292 ft
solve the equation
-3|3x+6|+2=9
Answer:
x= -0.36
firstly you need to open the brackets
-3(3x +6) + 2=9
-9x -18 + 2=9
secondly join the like terms together
-9x = 9 + 18 - 2
-9x = 25
thirdly you divide both sides by 25
-9x ÷ 25 = -0.36
x= -0.36
pls help I'm confused, oh and can you also explain it. 15pts
Answer:
6
Step-by-step explanation:
This triangle is a special right triangle. In triangles with the angles 30, 60, and 90, the side opposite of the 30 degree angle will always be half the length of the hypotenuse. The hypotenuse is the longest side of a right triangle. In a 30 60 90 triangle, the long side will be equal to the short side multiplied by the squareroot of 3, but that is not needed for this problem. Since the hypotenuse is 12, the side opposite of the 30 degree angle, labeled "s h o r t" will be half of 12. Half of 12 is equal to 6, therefore the short side will be equal to 6.

A point is reflected in the x-axis. The reflected point is (3,−9). What is the original point? The original point is ( , ). Question 2 What is the distance between the points? The distance between the points is units.
Answer:
The original point is [tex]P(x,y) = (3,9)[/tex].
The distance between the points is 18 units.
Step-by-step explanation:
The reflection of a point with respect to the x-axis is defined by the following operation:
[tex]P(x,y) = (x,y) \to P'(x,y) = (x, -y)[/tex] (1)
Where:
[tex]P(x,y)[/tex] - Original point.
[tex]P'(x,y)[/tex] - Resulting point.
If we know that [tex]P'(x,y) = (3, -9)[/tex], then the original point is [tex]P(x,y) = (3,9)[/tex].
The original point is [tex]P(x,y) = (3,9)[/tex].
The distance between the points ([tex]d[/tex]), in units, is determined vectorially by the following expression, which is equivalent to the Pythagorean Theorem:
[tex]d = \sqrt{[P'(x,y) -P(x,y)]\,\bullet\,[P'(x,y) -P(x,y)]}[/tex]
[tex]d = \sqrt{(0,18)\,\bullet (0,18)}[/tex]
[tex]d = \sqrt{0^{2}+18^{2}}[/tex]
[tex]d = 18[/tex]
The distance between the points is 18 units.
Answer:(3,9) Distance 18 units.
Step-by-step explanation:
Which expression is equivalent to x2 + 2x + 2
a. (x + 1 - i ) (x + 1 + i)
b. (x - 1 + i) (x - 1 - i)
c. (x + 1 - i ) (x + 1 - i)
d. ( x + 2) (x + 1)
The answer is Option A.
x + 1 - i ) (x + 1 + i)
Solution:
x (x+2) +2
(x+1)² + 1
= (x + 1 - i ) (x + 1 + i)
Answer:
Step-by-step explanation:
for the expression you wrote: x2 + 2x + 2 the answer is: none
the expression you have there is: x² + 2x + 2 and the answer is: a
by expanding a:
(x + 1 - i ) (x + 1 + i) = x² + x + xi + x + 1 + i - xi - i + 1
(x + 1 - i ) (x + 1 + i) = x² + x + x + 1 + 1
(x + 1 - i ) (x + 1 + i) = x² + 2x + 2

Given that m∠a = 93° and m∠b = 71°, find m∠x and m∠y.
m∠x =
°
m∠y =
°
Step-by-step explanation:
angle b = 71°
so, x + b = 180° ( linear pair )
x + 71° = 180°
x = 180° - 71°
x = 109°
Now, a + y = 180° ( linear pair )
93° + y = 180°
y = 180° - 93°
y = 87°
Hence, the value of x is 109° and y is 87°.

To solve the above equation we will follow the BODMAS rule.
[tex]\small\pink\bull[/tex] BODMAS is an order of mathematic operations.[tex]\small\pink\bull[/tex] BODMAS rule is to be followed while solving expressions in mathematics.It stands for :
[tex]\begin{gathered}\quad\begin{gathered} \small \begin{array}{l} \star \: \rm B= bracket \\\star \: \rm O= order \: of \: power \: \\\star \: \rm D= division \\\star \: \rm M= multiplication \\ \star \: \rm A= addition \\ \star \: \rm S=subtraction \end{array}\end{gathered}\end{gathered}[/tex]
Solving the question by bodmas rule :
[tex]\implies\tt{\dfrac{15 - 7 + 3(6 + 2)}{{2}^{3}}}[/tex]
[tex]\implies\tt{\dfrac{15 - 7 + 3(8)}{2 \times 2 \times 2}}[/tex]
[tex]\implies\tt{\dfrac{15 - 7 + 3 \times 8}{4\times 2}}[/tex]
[tex]\implies\tt{\dfrac{15 - 7 + 24}{8}}[/tex]
[tex]\implies\tt{\dfrac{39- 7}{8}}[/tex]
[tex]\implies\tt{\dfrac{32}{8}}[/tex]
[tex]\implies\tt{\cancel{\dfrac{32}{8}}}[/tex]
[tex]\implies\tt{\underline{\underline{\red{4}}}}[/tex]
Hence, the answer is 4.
