Answer:
x = 9
Perimeter = 74
Area = 342
Step-by-step explanation:
First, find x. to do so, set your formula up as
18 = 8x - 54
18 + 54 = 8x
72 = 8x
72/8 = x
9 = x
Now that you have x, find your missing side
2x + 1 = y, x
2 * 9 + = y
19 = y
Your perimeter is P = 2(l+W)
P = 2(18 * 19)
P = 74
Your area is A = wl
A = 19 * 18
A = 342
Answer:
x=9
Perimeter:76 ft
Area:342 ft^2
Step-by-step explanation:
x:
8x-54=18
Then solve for x.
Perimeter: add all sides
(2(9)+1)+(2(9)+1)+18+18
Area: multiply length and width
18 x 19 = 342

0.8/0.2=4
Express in simplest radical form. 48
Answer: 4[tex]\sqrt{3\\}[/tex]
Step-by-step explanation:
It is because to get rid of radical of 48, because you factor 48 and it comes out to be 12 and 4, factor of 4 is 2 x 2. Factor of 12 is 6 x 2. Simplify the 6 to
3 x 2. You find the pair and the ones that have a pare become one and go outside of the radical sign on the left. 2 has 2 pairs so it is only 2 x 2 = 4. So 4 goes outside of the radical sign. Then the number that is alone with no pair is 3 so you put the number 3 inside the radical sign.
4[tex]\sqrt{3}[/tex] is your answer.
Hope this helps, sorry if not...

Given:
A figure of a right angle triangle.
To find:
The length of BC.
Solution:
In a right angle triangle,
[tex]\tan \theta =\dfrac{Perpendicular}{Base}[/tex]
In the given triangle,
[tex]\tan A =\dfrac{BC}{AC}[/tex]
[tex]\tan 23^\circ =\dfrac{BC}{6}[/tex]
[tex]0.42447\times 6 =BC[/tex]
[tex]2.54682 =BC[/tex]
Approximate the value to the nearest hundredth.
[tex]BC\approx 2.55[/tex]
Therefore, the measure of side BC is 2.55 units.

f(x) = 3x - 1 and g(x) = x + 2, find (f+9)(x).
Answer:
what is this it looks so hard I don't have the answer
Answer:
(f + g)(x) = 4x + 1
Step-by-step explanation:
f(x) = 3x - 1
g(x) = x + 2
(f + g)(x) = f(x ) + g(x)
= 3x - 1 + x + 2
= 4x + 1

Step-by-step explanation:
The cost of having a window fixed is $100 plus $20 per hour of labor. Using h for the number of hours of labor, write an expression that represents the total cost.
Answer: 100+20h=x
Step-by-step explanation:
100 for the cost of the window Plus $20 times amount of hours the person does i equal the total amount you want to get which is x
Answer:
100 + (20 x H)
Step-by-step explanation:
100 dollars plus the amount paid for each hour of labor, so it would be 20 x H. Altogether it should be 100 + (20 x H).

what is the median of 4, 4, 7, 13, 12, 9
Answer:
8.11
Step-by-step explanation:
4+4+7+13+12+9 = 49
divide that by 6
========================================================
Explanation:
Sort the data set to go from {4,4,7,13,12,9} to {4,4,7,9,12,13}
Next, cross off the first and last items to get this smaller set: {4,7,9,12}
Repeat the last step to get this even smaller set: {7,9}
We can see that 7 & 9 are tied for the middle most positions. Add them up and divide by 2 to find the midpoint
(7+9)/2 = 16/2 = 8
The median is 8
The cost to play the game is $2. The winner gets $6 for making green. Suppose 36 people play the game. How much money will the school take in from this game before giving out prize money? *
Answer:
$72
Step-by-step explanation:
I did 36 x 2. I did not subtract the -6 for the prize money because it says not to.
Answer:
$72
Step-by-step explanation:
You are trying to determine how much money the school will take in before giving out prize money. Knowing this, you can actually ignore the $6 that the winner will get because you are not worried about giving out the prize money yet. You are only worried about how much you will make before the prize money.
So, you can do simple multiplication to find the answer:
price per game * amount of people playing game = money made from games
$2 * 36 = x
$72 = x

Select the ratio that represents sin(x)
A) 21/29
B) 29/21
C) 20/29
D) 20/21
E) 29/20
F) 21/20
Answer:
C
Step-by-step explanation:
sine uses opposite over hypotenuse
the opposite of x is 20 and the hypotenuse is 29
so the answer is 20/29
1. Provide an example of a variable term.
2. Provide an example of a constant term.
3. When looking at an expression and/or equation, how can we tell that we need to distribute?
4. When solving an equation, if you get the solution, x=0, how many solutions to the equation are there?
(One solution, no solution, or infinite solutions)
5. When solving an equation, if you get 5 = 11, what does this mean? (One solution, no solution, or infinite
solutions)
6. When solving an equation, if you get 5 = 5, what does this mean? (One solution, no solution, or infinite
solutions)
Answer:
Step-by-step explanation:
1) a variable term contains a variable. If x is a variable
5x is an example of a variable therm
2) a constant therm is not a variable
3 is an example
3) for example when a number multiply a sum or a difference between a constant and a variable
Example:
2(x-3) = 5(x+4)
4) one solution: only if x is equal to 0 the equation is true
5) no solution: the equation can’t be true for ever value of the variable
6) infinite solutions: the equation is ever true for every value of the variable

Which value of x is in the domain of f(t) = squared x - 7
O A. x= 8
O B. x = 0
C. x= -3
O D. x = 6
SUBMIT
Given:
The given function is:
[tex]f(x)=\sqrt{x-7}[/tex]
To find:
The value of x that is in the domain.
Solution:
Domain is the set of input values.
We have,
[tex]f(x)=\sqrt{x-7}[/tex]
We know that the square root is defined for non negative values. So,
[tex]x-7\geq 0[/tex]
[tex]x\geq 0+7[/tex]
[tex]x\geq 7[/tex]
Thus, the domain of the given function is all real number that are greater than or equal to 7.
In the given options 0, -3, 6 are less than 7 but 8 in option A is the only value that is greater than 7. So, [tex]x=8[/tex] is in the domain of the given function.
Therefore, the correct option is A.
Evaluate 32 + (7 − 2) ⋅ 4 − 6 over 3 . (1 point)
Answer:
50
Step-by-step explanation:
Given:
32 + (7 − 2) ⋅ 4 − 6/3
Using the acronym PEMDAS
P = parenthesis
E = Exponential
M = Multiplication
D = Division
A = Addition
S = Subtraction
32 + (7 − 2) ⋅ 4 − 6/3
= 32 + (5) • 4 - 6/3
= 32 + 20 - 6/3
= 32 + 20 - 2
= 52 - 2
= 50
Therefore,
32 + (7 − 2) ⋅ 4 − 6/3 = 50
