Answer:
Option a, (x-26)x
Step-by-step explanation:
Length is 26 units less than its width, let the length be x, so the width is x+26, so it's area will be their multiplication,
x(x+26)
since the formula to find area is (length×width)
However thing to note, if you assume the width to be x, the the length will be (x-26), so here the area becomes (x-26)x
since here the length is less than width, (x-26)x is the answer we will use.

Surface Area =
Answer:
The Surface area is 148
Step-by-step explanation:
For the front and back each side is 30 since 6x5=30. Therefore total 60
For the left and right it is 5x4=20. Each side 20 therefore total 40
For top and bottom it is 6x4=24. 24x2 =48 so total 48.
In total combined: 40+60+48=148

Find the total surface area of the rectangular prism in square millimeters. 2cm 6 cm 9cm
==============================================
Work Shown:
L = 2 = lengthW = 6 = widthH = 9 = heightThe order of length, width and height doesn't matter
SA = surface area of rectangular prism
SA = 2*(LW + LH + WH)
SA = 2*(2*6 + 2*9 + 6*9)
SA = 2*(12 + 18 + 54)
SA = 2*(30+54)
SA = 2*(84)

What is a function?
A function of an expression, rule, or law that defines the relationship between one variable (independent variable) and another (dependent variable) in mathematics. Functions are ubiquitous in mathematics and are essential for the formulation of physical relationships in the natural sciences.
Functions can be defined as a set of ordered pairs. Example: {(2,4), (3,5), (7, 3)} is a function that says. "2 is associated with 4," "3 is associated with 5," and "7 is associated with 3." Also note that the domain is {2,3,7} (input value). A
function is defined as a relationship between a set of inputs, each with an output. Simply put, a function is a relationship between inputs, where each input is associated with one output. Each function has a domain and a codomain or scope.

To find the exact value of tan(7π/12).
What are trigonometric equations?These are the equation that contains trigonometric operators such as sin, cos.. etc.. In algebraic operation.
[tex]tanx =\sqrt{ \frac{1 -cos2x}{1 + cos2x} }[/tex]
tan(7π/12) = √ [ (1 - cos2(7π/12) ) / (1 + cos2(7π/12) ]
= √ [ (1 - cos(7π/6) ) / (1 + cos(7π/6) ]
= √ [ (1 - cos(π + π/6) ) / (1 + cos(π + π/6) ]
Since cos(π + x) = -cosx
= √ [ (1 + cos(π/6) ) / (1 - cos(π/6) ]
Here, cos( π/6 ) = √3/2
= √ [ (1 + √3/2 ) / (1 - √3/2 ]
= √ [ (2 + √3)/2 / (2- √3)/2 ]
= √ [ (2 + √3) / (2- √3) ]
Thus, the required value of tan (7π/12) = √ [ (2+√3)/(2-√3) ].

I have part A I need help with b
Part B
Decking costs $1.75 per square foot. How much will it cost to build the deck?
Complete question is;
The blueprint of a deck has a scale of 2 centimeters equals 9 feet.
A) What are the actual lengths of the sides of the deck?
B) Decking costs $1.75 per square foot. How much will it cost to build the deck?
Answer:
A) actual lengths are;
27 ft, 36 ft and 45 ft
B) cost of entire deck = $850.5
Step-by-step explanation:
A) From the attached image, we see that the sides of the triangle deck are;
8cm, 10cm and 6 cm
Now, we know that 2cm represents 9 ft.
Thus;
8cm will be; 8 × 9/2 = 36 ft
10 cm will be; 10 × 9/2 = 45 ft
6 cm will be; 6 × 9/2 = 27 ft
Thus, actual lengths are;
27 ft, 36 ft and 45 ft
B) Area of deck is Area of triangle = ½ × base × height.
In this diagram, base = 6 cm = 27ft
Height = 8 cm = 36 ft
Thus;
Area of deck = ½ × 27 × 36
Area of deck = 486 ft²
We are told that the Decking costs $1.75 per ft²
Thus;
Cost of entire deck = 1.75 × 486 = $850.5

Mustafa’s soccer team is planning a school dance as a fundraiser. The DJ charges $200 and decorations cost $100. The team decides to charge each student $5.00 to attend the dance. If n represents the number of students attending the dance, which equation can be used to find the number of students needed to make $1,500 in profit?
5n – 300 = 1,500
5n + 300 = 1,500
5n – 200 + 100n = 1,500
5n – 100 – 200n = 1,500
Answer:
The first one, A
Step-by-step explanation:
DJ costs $300 in total.
For every student there is $5.
We want a profit of 1,500, so the total money earned from students attending subtracted by the costs of the DJ should be 1,500.
5n - 300 = 1,500
For the second one, it'll be the DJ giving you $300.
The last Two answers has an n where it's supposed to be money when n represents each student.

What is mid point theorem?The midpoint theorem states that the line segment joining the midpoints of any two sides of a triangle is parallel to the third side and equal to half of the length of the third side. This theorem is used in various places in real life, for example in the absence of a measuring instrument, we can use the midpoint theorem to cut a stick into half.
Midpoint Theorem FormulaIn math, we also have a midpoint theorem formula which has its applications in coordinate geometry. It can also be known as the midpoint theorem of a line segment. It states that if we have a line segment whose endpoints coordinates are given as (x1, y1) and (x2, y2), then we can find the coordinates of the midpoint of the line segment by using the formula given below:
Let (xm, ym) be the coordinates of the midpoint of the line segment. Then,
(xm, ym) = ( (x1 + x2)/2 , (y1 + y2)/2 )
This is known as the midpoint theorem formula.
As, midsegment is half the sum of the parallel bases
21 - x = 1/2 (17 + 11)

a meat pie contains chicken and turkey in the ratio 4:1. The pie contains 200g of Chicken. How much turkey is in the pie?
Answer:
50 grams
Step-by-step explanation:
From the above question:
Chicken : Turkey
= 4:1
Sum Proportions = 4 + 1 = 5
We have to find the weight in grams of the entire pie
Let us represent the weight in grams of the entire pie = x.
The pie contains 200g of Chicken.
Hence:
4/5 × x = 200g
4x/5 = 200g
Cross Multiply
4x = 200g × 5
x = 200g × 5/4
x = 250g
The amount turkey that is in the pie is calculated as:
Total weight of pie - Amount of Chicken in the pie
= 250g - 200g
= 50 g
