Answer:
x = 1
Step-by-step explanation:
4x + 8 = 12x
4 (1) + 8 = 12 (1)
4 + 8 = 12
12 = 12
your answer is x = 1
Answer:
4x+8=12x
8=8x subtract 4 on both sides
1=x divide by 8 on both sides

42 square feet
Step-by-step explanation:
If you turn the shape into a trapezoid, rectangle and triangle you can figure out the area for each one.
1. The area of a rectangle is b⋅h or 7⋅3 and you get 21.
2. The area of a triangle is 1/2⋅bh or 0.5 ⋅ 3 ⋅2 and you get 3.
3. The area of a trapezoid is 1/2(b1 + b2) ⋅ h or 0.5 ⋅ (6 + 3) ⋅ 4 and you get 18.
4. Then you add all areas together(18+3+21) and get 42.

Dustin has a spinner that is divided into 5 equal-size sections colored pink, blue, orange, white, and green. What is the probability that Dustin spins pink on the 1st spin and then spins a color other than pink on the 2nd spin?
Answer:
1/6
Step-by-step explanation:
1st spin:
1 out of the 5 sections are pink, so the probability of spinning a pink on the 1st spin is 1/5.
2nd spin:
5 out of the 6 sections are not pink, so the probability of spinning a pink on the 2nd is 5/6.
Multiply the probabilities of the two spins to get the answer.
[tex]\frac{1}{5} *\frac{5}{6} =\frac{5}{30} =\frac{1}{6}[/tex]

Answer:
B) 63 ft.
Step-by-step explanation:
To find how long it takes for a rotation, we need to find the circumference.
To do so, we use the formula 2(pi)r
To find the radius, we divide the diameter in half :
d = 20
r = d/2
r = 20 / 2
r = 10
Then, we plug that into the formula :
2(pi)10
Insert that into your calculator :
2(pi)10 = 62.83
Simplify :
62.83 = 63 ft.

The radius of a circle is 2 meters. What is the circle's area?
(use 3.14 for π)
Answer:
it is approximately 12.57meters
Answer:
12.56 meters
Step-by-step explanation:
The area of a circle is πr², where r is the radius of the circle.
First we square the radius, which is 2. 2²=4.
Now our area is 4π.
Using 3.14 for π, we can say the area is 4 × 3.14, which is equal to 12.56

find the total surface area of the prism 10 2 6
Answer:
88 units
Step-by-step explanation:
First, we need to find the surface area of each side of the prism. Assuming this is a rectangular prism, judging by the dimensions, that makes things easier.
10*2=20
We'll multiply 20 by 2 since there are 2 sides with these dimensions, resulting in 40 units.
2*6=12
We'll multiply that by 4 since there are 4 sides with these dimensions, resulting in 48 units.
Adding 48 to 40, we get 88.
Hope that helped.
Find the 3rd term in the expansion of (a+b)^8 in simplest form.
Answer:
The fifth term is the middle term of nine, with coefficient given by all the ways of choosing 4 items out of 8 , namely the ways of choosing 4 a 's out of 8 binomial factors.
Step-by-step explanation:
The third term of the expansion is 56a⁵b³
How to determine the third term?The expression is given as:
(a + b)^8
The above expression is a binomial expression, and the nth term of the expression is:
(a + b)^n = nCr * a^(n - k) * (b)^k
Where k = 0, 1, 2.....
So,we have:
(a + b)⁸ = ⁸C₃ * a⁸⁻³ * b³
Evaluate the combination expression
(a + b)⁸ = 56a⁵b³
Hence, the third term of the expansion is 56a⁵b³

If the perimeter of the polygon is 42, AB = ______?
Answer:
AB = 7
Step-by-step explanation:
The polygon pictured is a hexagon, which means that it has 6 equal side lengths. The perimeter is 42. AB is the length of one side.
Perimeter = 6 x length of one side
If you plug everything you know in the equation, you would get...
42 = 6 x length of one side
42 ÷ 6 = 7
So, 7 is the length of AB, since in a hexagon, all sides are the same length.
The length of side AB is 7.
What are regular polygons?A regular polygon is a closed shape that has straight sides of equal length and interior angles of equal measure.
This means that all of the sides and angles of a regular polygon are congruent (i.e., have the same size).
We have,
The given polygon is a hexagon since it has 6 faces.
Now,
The six faces are equal in length.
So,
6 faces length = 42
Now,
Each face = x
And,
6x = 42
x = 42/6
x = 7
Thus,
The length of AB is 7.
