Answer: [tex]5x\sqrt{3x}[/tex]
Step-by-step explanation:
The factors of 75 are 5, 5, and 3. Since there are two 5's, we can take the square root of them to get 5. x^3 has x, x, and x. There are also two x's, which means that we can square root them to equal just x.

Find the area of each square given the side S or the perimeter P. S = 2 yd Thank you if u r helping me!
Answer:
I think the perimeter is 8 yd
Step-by-step explanation:
Because it's a square, if one side is 2 yd then we can assume that the remaining 3 sides are also 2 yd long. So, 2 yd + 2 yd + 2 yd + 2 yd = 8 yd

What is the circumference, in centimeters, of the circle? Use 3.14 for n. Enter your answer in the box
Answer:
75.36
Step-by-step explanation:
The circumference of a circle is just the diameter, 24 in this question times 3.14.
The solution is, 75.36 cm is the circumference, in centimeters, of the circle.
What is perimeter?A perimeter can be mentioned as a closed path that encompasses, surrounds, or outlines either a two dimensional shape or a one-dimensional length. The perimeter of a circle or an ellipse is called its circumference. Calculating the perimeter has several practical applications.
Perimeter means to the total outside length of an object,
here, we have,
the diameter, 24 cm (in this question)
now, we have to find the circumference,
we know that,
The circumference of a circle is the diameter times 3.14.
so, we get,
the circumference = 24*3.14 cm
=75.36cm
Hence, The solution is, 75.36 cm is the circumference, in centimeters, of the circle.

Find the sum of the numbers as a product of their GCF is 84 + 108
Hey there! :)
I believe the correct answer to your question is 12.
Find the prime factorization of 84
84 = 2 × 2 × 3 × 7
Find the prime factorization of 108
108 = 2 × 2 × 3 × 3 × 3
To find the gcf, multiply all the prime factors common to both numbers:
Therefore, GCF = 2 × 2 × 3
GCF = 12

Answer:
12 hrs
Step-by-step explanation:
6+18 =24
24/2 = 12
Answer: 4h 30min
Step-by-step explanation: Theoretically, if X= Number of hours required to paint the room,
X(1/6+1/18)=1
X(3/18+1/18)=1
X(4/18)=1
X(2/9)=1

Answer:The area is 14306. 625 cm.
Step-by-step explanation:
To find the area of the circle, we will need to find the diameter and find the radius.
So we know the circumference is 423.9 m and we know to get the circumference, you will need to multiply pie by the diameter .
so now we need divide the circumference by pie to find the diameter.
423.9/ 3.14 = 135 so 135 is the diameter.
To find the radius we need to divide the diameter by 2.
135/2 = 67.5
Now is time to find the area which uses the formula A= nr^2
A = 3.14 * 67.5^2
A = 14306. 625
1) Tanya is buying edging for a triangular flower garden she plans to build in her backyard. If the lengths of the three pieces of edging that she purchases are 13 feet, 10 feet, and 7 feet, will the flower garden be in the shape of a right triangle ?
Answer:
The Flower Garden is not in the shape of a right Δ
Step-by-step explanation:
~ To prove that this garden is in the shape of a right triangle, it can be done so through contradiction ~
Pythagorean Theorem is applied to a right triangle, so we can say that the two legs are 10 and 7 feet, the hypotenuse being 13, knowing it is the longest side;
a^2 + b^2 = c^2,
10^2 + 7^2 = 13^2,
100 + 49 = 169,
149 ≠ 169,
So the Flower Garden will not be in the shape of a right Δ
50 POINTS find the length of ab plz help me
Answer:
about 9.4 units
Step-by-step explanation:
Distance formula:
√(x1 - x2)² + (y2 - y1)²
Coordinates:
A (4, 2)
B (9, 10)
Let's make 9 = x1
Let's make 4 = x2
Let's make 10 = y1
Let's make 2 = y2
Substitute into the distance formula:
√(x1 - x2)² + (y2 - y1)²
√(9 - 4)² + (2 - 10)²
Solve:
√(9 - 4)² + (2 - 10)²
√(5)² + (-8)²
√25 + 64
√89
≈ 9.4
Therefore, the length of AB is approximately 9.4 units.
Answer:
About 9.4 units
Step-by-step explanation:
To find the distance between two points
d = sqrt(( y2-y1) ^2 + (x2-x1) ^2) where (x1,y1) and (x2,y2) are the points
= sqrt(( 10-2)) ^2 + (9-4) ^2)
= sqrt((8) ^2 + (5) ^2)
= sqrt(64+ 25)
= sqrt(89)
=9.433981132
About 9.4 units

The graph of f(x) = |x| is vertically stretched by a factor of 3, shifted left 2 units, shifted down 4 units and reflected over the x-axis. What is the function equation of the resulting graph?
Answer:
The final transformed function becomes:
[tex]f(x)=-3\,|x-2|+4[/tex]
Step-by-step explanation:
The first transformation (vertically stretched by a factor of 3) means we multiply by 3 the original function:
[tex]f(x)= 3\,|x|[/tex]
second transformation (shifted left 2 units) means we add 2 units to "x":
[tex]f(x)=3\,|x+2|[/tex]
third transformation (shifted down 4 units) implies that we subtract 4 units to the full functional expression:
[tex]f(x)=3\,|x+2|-4[/tex]
fourth transformation (reflected over the x-axis) implies that we multiply the full functional expression by "-1":
[tex]f(x)=(-1)\,(3\,|x+2|-4)\\f(x)=-3\,|x-2|+4[/tex]
Step-by-step explanation:
Step 1: Add the vertical stretch
[tex]f(x) = |x|[/tex]
[tex]f(x) = 3|x|[/tex]
Step 2: Shift it to the left 2 units
[tex]f(x) = 3|x|[/tex]
[tex]f(x) = 3|x + 2|[/tex]
Step 3: Shift it down 4 units
[tex]f(x) = 3|x + 2|[/tex]
[tex]f(x) = 3|x + 2| - 4[/tex]
Step 4: Reflect it across the x-axis
[tex]f(x) = 3|x + 2| - 4[/tex]
[tex]f(x) = -3|x + 2| - 4[/tex]
Answer: [tex]f(x) = -3|x + 2| - 4[/tex]

Marissa jumped 42 times in 7 hours. At that rate, how many times would she jump in 30 minutes?
Answer:
3
Step-by-step explanation:
Well first let's calculate how many times she jumped per hour. For that we need to divide 42 by 7 which is 6. Now we need to divide that by two because they are asking for every half hour, not every hour. So 6 divided by 2 is 3. So our answer is 3.

Point B has coordinates (3,2). The x-coordinate of point A is negative 3. The distance between point A and point B is 10 units. What are the possible coordinates of point A?
The possible coordinates of point A are
Answer:
Either A= (-3,10)
OR A= (-3,-6)
Step-by-step explanation:
A = (-3,y) B = (3,2)
(Distance from A to B) = √[(-3-3)²+(y-2)²]=10
√[36+y²-4y+4]=10
√[y²-4y+40]=10
squaring on both sides
y²-4y+40=100
y²-4y-60=0
y²-10y+6y-60=0
y(y-10) + 6 (y-10)=0
(y - 10)(y + 6)=0
Either y=10 =>A= (-3,10)
OR y=-6 =>A= (-3,-6)
