2(x+5)=20 what does x===???????????????????/
Answer:
x = 5
Step-by-step explanation:
2(x+5) =20 Distribute the 2
2(x) + 2(5) = 20
2x + 10 = 20 Subtract 10 from both sides of the equation
2x = 10 Divide both sides by 2
x = 5
Answer:
5
Step-by-step explanation:
2(x + 5) = 20 Divide both sides by 2
x + 5 = 10
x = 10 - 5
x = 5
Box A has a length of 5 feet, height of 1 foot, and width of 3 feet. Box B has a length of 4 feet, height of 3 feet, and width of 2 feet. Box C has a length of 7 feet, height of 2 feet, and width of 1 foot. Box D has a length of 3 feet, height of 3 feet, and width of 3 feet.
Lucas wants to use the box with the greatest volume. Which shipping box should he use?
Box
Lucas will be using the shipping box D as it is the box with the greatest volume of 27ft³
Volume of a rectangular boxThe volume of a rectangular box is calculated by multiplying its three dimensions which are the length, width, and height . That is Length × Width × Height in the same units.
volume of box A = 5ft × 3ft × 1ft
volume of box A = 15ft³
volume of box B = 4ft × 2ft × 3ft
volume of box B = 24ft³
volume of box C = 7ft × 1ft × 2ft
volume of box C = 14ft³
volume of box D = 3ft × 3ft × 3ft
volume of box D = 27ft³
Therefore, the shipping box with the largest volume is box D with 27ft³

Members of the student government are planning a movie night on campus. They have asked a random sample of students which of four movies the student would prefer. Here are the results Movie A- 31 students, Movie B- 27 students, Movie C- 34 students, Movie D- 28 students. There are 900 students total on campus. Based on the above information, how many students on campus would we expect to prefer Movie C? Round your answer to the nearest whole number. Do not round any intermediate calculations
There are 255 students who prefer Movie C.
In the given case, the total number of students in the campus = 900
Number of students in the random sample :
= 31 + 27 + 34 + 28
= 120
Number of students who prefer to watch movie C in the chosen sample:
= 34
To get number of students who would prefer to watch the movies C in the total population of 900, we can extrapolate the data from the chosen sample to the entire population.
Thus, number of students expected to prefer movie C in the campus =
34/120 × 900
= 255
Hence the expected number of students are 255.

Answer:
Step-by-step explanation:
the answer is "downward". If you say "why", it is because of the degree coefficient.
in the equation, the latest degree is 2 (which is quadratic equation) so from the degree its coefficient is -3. If it is negative, it should be downward like -3. But if it is positive it should be upward like 3, 1, 44.

Can someone lmk the answers
The value of the angle regarding the parallel lines are:
1. x = 14
2. x = 9
3. x = 17
4. x = 5
How to calculate the values?1. Lines 'l' and 'm' are the parallel lines and a transversal line is intersecting these lines.
(9x + 13)° = (12x - 29)° [Alternate interior angles]
9x - 12x = -29 - 13
-3x = -42
Divide
x = 14
2). By substituting x = 14 in the box.
(13x + 5)° + (8x - 14)° = 180° [Consecutive interior angles]
21x - 9 = 180
21x = 189
Divide
x = 189/21
x = 9
3). By placing x = 9 in the box,
(5x + 52)° = (9x - 16)° [Corresponding angles]
5x - 9x = -52 - 16
-4x = -68
x = 17
4). By placing x = 17 in the box,
(10x + 17)° = (12x + 7)° [Alternate exterior angles]
10x - 12x = -17 + 7
-2x = -10

It is 18 millimeters long in the drawing. What scale did Colton use?
By using unitary method it is obtained that -
Scale used my Colton = 1 : 500
What is unitary method?
Unitary method is the process in which the value of single unit can be calculated from the value of multiple unit and the value of multiple unit can be calculated from the value of single unit. Sometimes Value of single unit can be less than the value of multiple unit. For example - The relation between the cost of a commodity and the quantity of the commodity
Sometimes Value of single unit can be more than the value of multiple unit. For example - The relation between the number of men and the number of days taken by those men to do a certain job.
Here unitary method is used
18 mm long field in the drawing is equivalent to 9000 mm long field in real
1 mm long field in the drawing is equivalent to [tex]\frac{9000}{18}[/tex] mm long field in real

line DF = 27
line EF = 36
sin D =
sin E =
cos D =
cos E =
The value of each term is
sin D = 4/5sin E = 3/5cos D = 3/5cos E = 4/5The length of the line ED = 45 units
The length of the line DF = 27 units
The length of the line EF = 36 units
Here we have to use the trigonometric function
sin θ = Opposite side / Hypotenuse
cos θ = Adjacent side / Hypotenuse
Substitute the value in the equation
sin D = Opposite side / Hypotenuse
= 36/45
= 4/5
sin E = Opposite side / Hypotenuse
= 27/45
= 3/5
cos D = Adjacent side / Hypotenuse
= 27/45
= 3/5
cos E = Adjacent side / Hypotenuse
= 36/45
= 4/5

Which of the following is the correct factorization 64x^3+8?
The correct factorization of the expression, [tex]64x^{3} +8[/tex], is 4[tex](2x-1)^{2}[/tex] (8x+2).
According to the question,
We have the following information:
[tex]64x^{3} +8[/tex]
The factors of this expression can be found using identity because 64[tex]x^{3}[/tex] is the whole cube of 4x and 8 is the cube of 2.
So, we have the following expression:
[tex](4x)^{3} + 2^{3}[/tex]
Now, we can use the following identity to factor the given expression:
[tex]a^{3} +b^{3} = (a+b) (a^{2} -ab+b^{2} )[/tex]
We have a = 8x and b = 2:
(8x+2) {[tex](4x)^{2}[/tex]-16x+[tex]2^{2}[/tex]}
(8x+2) (16[tex]x^{2}[/tex]-16x+4)
Taking 4 as the common factor from the second bracket:
4(8x+2) (4[tex]x^{2}[/tex]-4x+1)
Now, finding the factors of second bracket:
4(8x+2) ([tex]4x^{2}[/tex]-2x-2x+1)
4(8x+2) {2x(2x-1)-1(2x-1)}
4(8x+2) (2x-1) (2x-1)
4[tex](2x-1)^{2}[/tex] (8x+2)
Hence, the correct factorization of the expression, [tex]64x^{3} +8[/tex], is 4[tex](2x-1)^{2}[/tex] (8x+2).

By taking some products we will see that the total number of cupcakes ordered is 6 cupcakes.
How many cupcakes are ordered?Here we want to see how many cupcakes this person is ordering. We know that orders 9 halves of a cupcake for the family, plus a quarter of a cupcake for each of the 6 friends.
The total number of cupcakes is given by the order for the family plus the order for the friends.
The order for the familiy is given by the product:
9*(1/2) = 9/2 = 4.5
That is 9 times 1/2 of a cupcake, so for the family the person orders 4.5 cupcakes.
For the friends the person orders 6 times 1/4 of a cupcake, so now we have the product:
6*(1/4) = 6/4 = 3/2 = 1.5
If we add these two numbers we get the total number of cupcakes:
4.5 + 1.5 = 6
