Answer:
B. -72n+60
Step-by-step explanation:
We are given the expression:
-8 (9n-10) -20
We want to simplify the expression. First, distribute the -8.
Multiply each term inside the parentheses by -8.
(-8 * 9n) + (-8*-10) -20
-72n + (-8 * -10) -20
-72n + 80 -20
Next, combine like terms. Currently, we have two constants (terms without variables) that can be combined.
Subtract 20 from 80.
-72n + (80-20)
-72n + 60
The expression: -8(9n-10)-20, simplified is -72n+60. Therefore, the correct answer is B. -72n+60

Jack plays basketball for 8 minutes and makes 14 points. If he plays for a total of 21 minutes, approximately how many points will Jack make?
So he makes 14 points per 8 minutes, and you need to find how many points he scores in 21 minutes.
[tex]\frac{8}{14} = \frac{21}{x}[/tex]
To get from 8 to 21, you have to multiply by 2.625
So do the same thing to the denominator; 14 × 2.625 = 36.75
Since 0.75 point is no point so you round down.
Jack scores 36 points in 21 minutes.
♡ Hope this helps! ♡

Given:
A(-12, -8). B(-12, 7), C(0, 16), D(12,7), E(12, -8), F(0, -17)
Find:
Perimeter of the hexagon
Computation:
Length = √(x1 - x2)² + (y1 - y2)²
AB = √(-12 + 12)² + (-8 - 7)²
AB = 15
BC = √(-12 + 0)² + (7 - 16)²
BC = 15
CD = √(0 - 12)² + (16 - 7)²
CD = 15
DE = √(12 - 12)² + (-7 - 8)²
DE = 15
EF = √(12 - 0)² + (-8 + 17)²
EF = 15
FA = √(0 + 12)² + (-17 + 8)²
FA = 15
Perimeter of the hexagon = AB + BC + CD + DE + EF + FA
Perimeter of the hexagon = 15 + 15 + 15 + 15 + 15 + 15
Perimeter of the hexagon = 90 Unit

you are given the expressions 76+n and 2n + 26. What is the smallest value of n that will make each number rational?
Answer:
The smallest value of n is 5.
Step-by-step explanation:
The expressions provided are:
[tex]1. \sqrt{76+n}\\\\2. \sqrt{2n+26}[/tex]
Rational numbers are those numbers that can be expressed in ratio or fractional form, i.e. in the form of [tex]\frac{p}{q}[/tex].
The provided numbers have denominators as 1.
We need to find the minimum value of n to make both the numbers a perfect square.
Consider the first number,
[tex]\sqrt{76+n}=\sqrt{76+5}=\sqrt{81}=9[/tex]
The number [tex]\frac{9}{1}[/tex] is a rational number.
Consider the second number,
[tex]\sqrt{2n+26}=\sqrt{(2\times5)+26}=\sqrt{36}=6[/tex]
The number [tex]\frac{6}{1}[/tex] is a rational number.
Thus, the smallest value of n is 5.

Attachment 1 : The sum of all exterior angles in any regular polygon will be 360 degrees, so if an exterior angle is found to be 30 degrees, it will have 360 / 30 sides. Therefore 360 / 30 = 12 sides
Attachment 2 : This figure is a concave quadrilateral. You can tell by it's shape, but also as one interior angle, in this case ∠KLM, is greater than 180 degrees.
Attachment 3 : As you can see the missing number is simply sum of the numbers provided on the left. Therefore the missing number will be the following,
1³ + 2³ + 3³ + 4³ + 5³ = 1 + 8 + 27 + 64 + 125
= 125
Attachment 4 : This is an example of the associative property, as it allows you to re - group the numbers. Your solution will be " Associativity. "
Attachment 5 : The cube of a negative integer will always result in a negative integer. Let's take - 3 as an example,

CBG is an isolesis triangle
angle G and CBG is X
angle BCG=180-90-12=180-78=102
X=(108-102)/2=39
Answer:39°
Step-by-step explanation:
If you know some properties of circle you may solve it like this:
Since ∠CDF = 90°, FC is the diameter of the circle passing through C, D and F.
So B is the centre of the circle mentioned above as B is the mid-point of FC.
Then we have BF = BC = BD since they are all radii of the same circle.
∠BDF = ∠BFD = 12°
∠BDA = 90° + 12° = 102°
∠BDA + ∠BAD + ∠ABD = 180°
102° + x + x = 180°
x = (180° - 102°)/2 = 39°

Write an equation in point – slope form from the line through the given point with the given slope. (-10, -1); m=-1
Answer:
y = -x - 11
Step-by-step explanation:
We know the equation must be: y = -x + c
However we do not know what "C" is. If we plug in our x and y values then we can find out the value of C.
So:
-1 = -(-10) + c
-1 = 10 + c
so c = -11
So our equation is:
y = -x - 11

4x-1=4x+7 regroup/ divide by the number next to x
Answer:
x = ∞Step-by-step explanation:
Given the expression 4x-1 = 4x+7, we are to simplify the expression and find the value of x. To do that the following steps must be carried out.
Step 1: collect the like terms by regrouping the expression
4x-1 = 4x+7
4x - 4x = 7+1
0x = 8
Step 2: Dividing both sides by the number next to x
0x/0 = 8/0
x = ∞
Any constant dividing zero will always return infinity as a value.

Se vendieron para una función en el teatro 255 entradas a $130,antes del comienzo de la función,hubo 5 devoluciones,pero luego se vendieron dos entradas más¿cuantas personas asistieron a la función?¿cuanto dinero se recaudó?
Answer:
Asistieron 252 personas
Se recaudó una cantidad de $ 32760.
252 people attended the show.
$ 32760 amount was raised.
Step-by-step explanation:
Spanish
Número total de entradas = 255
Costo de un boleto = $ 130
Costo total = Número total de boletos * Costo de 1 boleto
= 255 * 130 = $ 33150
Entonces se devolvieron 5 boletos y se vendieron dos más. La cantidad devuelta fue (5-2) * 130 = $ 390
Restando $ 390 de $ 33150 da $ 32760.
Asistieron 252 personas.
Como
255-5 + 2 = 252
y
Se recaudó una cantidad de $ 32760.
Esto también se puede resolver multiplicando = $ 130 * 252 = $ 32760
English
Total number of tickets = 255
Cost of one ticket = $ 130
Total Cost = Total Number of tickets * Cost of 1 ticket
= 255 * 130= $ 33150
So 5 ticket was returned and two more were sold. The amount returned was (5-2) * 130= $ 390
Deducting $ 390 from $ 33150 gives $ 32760.
252 people attended the show.
As
255-5 + 2= 252
and
$ 32760 amount was raised.
This can also be solved by multiplying= $ 130 *252= $ 32760
The width and the length of a rectangle are consecutive even integers. If the width is decreased by 3 inches, then the area of the resulting rectangle is 24 square inches. What is the area of the original rectangle
Answer:
Original Area : 48 square inches
Step-by-step explanation:
Let's say that the width of this rectangle is x, and the length of this rectangular is y. Remember that they are even consecutive integers as well, so let's make the length 2 greater than the width.
x = width,
x + 2 = length
And remember that the width decreases by 3 inches, to result in a rectangle of area 24. So the width will be x - 3, and the area will be (x - 3)(x + 2). Therefore we have the quadratic equation (x - 3)(x + 2) = 24, in which we can solve for x and y to determine the area of the original rectangle.
Step # 1 : Expand the expression (x - 3)(x + 2),
x² - x - 6 = 24
Step # 2 : Simplify and factor the expression x² - x - 6
x² - x - 30 = 0 ⇒ (x + 5)(x - 6) = 0
Step # 3 : Apply the Zero Factor Principle
x + 5 = 0, and x - 6 = 0
x = - 5, x = 6
Now remember that the width can't be negative, so it will be 6 inches long. That would make the length 6 + 2 = 8 inches. The area of the original rectangular will be 6 [tex]*[/tex] 8 = 48 square inches.
Answer:
48 square units
Step-by-step explanation:
Let L and W represent the length and width of the rectangle.
L = W +2 . . . . . . assuming the length is more than the width
L(W -3) = 24 . . . . the area after the reduction in width
__
(W +2)(W -3) = 24
So, we're looking for factors of 24 that differ by 5. We know that 24=8·3, so we have ...
W+2 = 8
W = 6 . . . . . . . matches W-3=3, also
Then the length is ...
L = W+2 = 8
and the area of the original rectangle is ...
A = LW = (8 inches)(6 inches) = 48 square inches
