12. The perimeter of a rectangle is 50 feet. The width is 5 less than the
length. What are the dimensions of the rectangle? (Write your answer as
Length, Width)
Step-by-step explanation:
Length = x
Width = (x-5)
Perimeter = 2 lengths + 2 widths
50 ft = x + x + (x-5) + (x-5)
50 ft = 4x - 10
60 ft = 4x
15 ft = x
length = x = 15 ft
width = (x-5) = (15 -5) = 10 ft
dimensions = length × width
= 15 ft × 10 ft
if you wanna check,
50 ft = x + x + (x-5) + (x-5)
50 ft = 15 + 15 + (15-5) + (15-5)
50 ft = 30 +(10+10)
50 ft = 30 + 20
50 ft = 50

I need help with #8. I need to use the quadratic formula. I have a calculator that is programmed for the quadratic formula so all I need are the a, b, and c values. for this problem, I am required to show any equations used to solve for the variable. hope you can help me, thanks!!
Answer:
x = 14
Step-by-step explanation:
Extend line AB so that it intersects ray CE at point G. Then angles BGC and BAD are "alternate interior angles", hence congruent.
The angle at B is exterior to triangle BCG, and is equal to the sum of the interior angles at C and G:
138 = (376 -23x) +(x^2 -8x)
Subtracting 138 and collecting terms we have ...
x^2 -31x +238 = 0
For your calculator, a=1, b=-31, c=238.
__
Additional comment
You will find that the solutions to this are x = {14, 17}. You will also find that angle BCE will have corresponding values of 54° and -15°. That is, the solution x=17 is "extraneous." It is a solution to the equation, but not to the problem.
For x=14, the marked angles are A = 84°, C = 54°.

PLEASE HELP .. At the beginning of the school year, the number of students in the band was the same as the number of students in the choir. Throughout the school year, the number of students in the band decreased by 8, and the number of students in the choir decreased by 4. At the end of the school year, the number of students in the choir was 25% more than the number of students in the band. How many students were in the band at the beginning of the school year?
A team is playing a game and currently has 43 points. If they lose 56 points and then gain 13 points, what will their score be? Write an expression that models this situation and evaluate the expression.
Answer:
(43 - 56) + 13 = 0 points
Step-by-step explanation:
We start with 43 points and loose 56 -- 43-56
then, 13 points are gained = (43 - 56) + 13
simplify and solve:
-13 + 13 = 0
*Note: you can write the expression without the brackets

True or False? In reference to different sampling methods, systematic sampling includes the steps: list the members of the population; use simple random sampling to select a starting point in the population; let k = (number of individuals in the population)/(number of individuals needed in the sample); choose every kth individual in the list starting with the one that was randomly selected.
Answer:
True
Step-by-step explanation:
In the simple random sampling every individual in the population has an equal chance to be selected in the sample. Systematic sampling is a probability sampling in which selection of elements is made from order frame. These samples are selected based on intervals of the population.
Find three consecutive EVEN integers such that the sum of the smallest number and twice the middle number is 20 more than the largest number.
Answer:
10, 12 and 14Step-by-step explanation:
x - an integer
2x - an even integer (the first and the smaller of the three)
Consecutive integers increase always by 2
2x+2 - next even integer consecutive to 2x (the middle one)
2x+2+2=2x+4 - the last consecutive even integer (the largest)
2•(2x+2) - twice the middle number
2x+2•(2x+2) - the sum of the smallest number and twice the middle one
2x+4+20 - 20 more than the largest number
2x+2•(2x+2) = 2x+4+20
2x + 4x + 4 = 2x + 24
-2x -2x
4x + 4 = 24
÷2 ÷2
2x + 2 = 12 ← the middle number
-2 -2
2x = 10 ← the smallest number
2x+4 = 10 + 4 = 14
Check: 10+2•12=34; 14+20=34

PERIMETER IS ADDING ALL SIDES, AREA IS MULTIPLYING TWO SIDES
1. 2 1/9
2. 42.25
3. 4
4. 87
Answer:
perimeter is adding up all the outside line measures, so for the squares with only one side value, just multiply that by four
the other ones, for the measure given for one side, the opposite side is the same measure, so just add that up.
so number one would be 9 and 1/3 (nine and one third)

Levi bought 14 chicken wings for $22.40 how much would it cost for 12 wings
Answer:
x =19.20
Step-by-step explanation:
We can use ratios to solve
14 wings 12 wings
------------- = ---------------
22.40 x
Using cross products
14x = 22.40 * 12
14x =268.8
Divide each side by 14
14x/14 = 268.8/14
x =19.20
1. Point M is on PQ, PM has a length of 7 units, and point N is the midpoint of MQ. If the length of NQ
is 4 units, how long is PQ?
PA
A 3 units
B. 11 units
C. 15 units
D. 18 units
Answer:
C. 15 units
Step-by-step explanation:
PM = 7 units
p..............M..........N............Q
7 unit 4 unit
NQ = 4 units
Given that
N is midpoint of MQ
it means N divides MQ into two equal parts
thus
MN = NQ = 4 units
now
we have to find length of PQ
p..............M..........N............Q
7 unit 4 units 4 unit
PQ = PM + MN + NQ
PQ = 7 units + 4 units + 4 units = 15 units
thus, correct answer is option c 15 units
Answer:
15 units

Let
f(x) = {3x - 7}/{x + 1] Find the range of f.
Give your answer as an interval.
Answer: Range = (-∞, 3) U (3, ∞)
Step-by-step explanation:
The range is the set of all y-values in a function. The easiest and most straightforward way to find the range is to graph the function and find asymptotes, or locations on the graph where the function lacks y-values.
You can plug in a few points to the equation, as shown in this table below.
After you have your points, you can draw your function following the points, as shown in the next image. Notice the line at y = 3, where the function does not cross. Although it will get infinitely close to the line, the function will never meet or cross this point at any x-value. This is what is known as a "horizontal asymptote", and is not included in the range of the function.
We can represent this asymptote in a range, which is a representation of all possible y-values in the function. The possible y-values for this function start at negative infinity and end at infinity, but do not exist at y = 3, so we represent this through this mathematical expression:
Range = (-∞, 3) U (3, ∞)
