Answer:
28 inch
Step-by-step explanation:
half of 38 would be 19, and take away 5 from both 19. Equally each width ( top and bottom ) 14 inch and each lenght ( Left and right ) 5 inch. so x representing width would be 14 + 14= 28 inch.

given the f(X)=2x+3/x-1 and g(X)=3x+1
a.)evaluate
i.)fg(-1)
Evaluation of fog(-1) = 1/3
Given,
f(X)=2x+3/x-1
g(X)=3x+1
a) Evaluate:
(f o g)(x) = f(g(x))
= 2(g(x)) + 3/(g(x)) - 1
= 2(3x + 1) + 3/(3x + 1) - 1
= 6x+2+3/3x+1-1
(f o g)(x) = 6x+5/3x
i) fog(-1) = 6(-1)+5/3(-1)
= -6+5/-3
= -1/-3
fog(-1) = 1/3
Hence, a.)evaluate: (f o g)(x) = 6x+5/3x
i.)fg(-1): fog(-1) = 1/3

Prove that the measures of the exterior angles of a triangle have a sum of 360°.
Given: <1, <2, and <3 are exterior angles.
Prove: m<1 +m<+m<3 = 360
Sum of Exterior Angles of Triangle is 360°.
Define Exterior Angle
The angle between any side of a shape and a line that extends from the next side is known as the exterior angle.
Let's Prove: ∠1 + ∠2 + ∠3 = 360°
The angle that is created between one of a triangle's sides and its adjacent extended side is known as the external angle. A triangle has three external angles. Let's learn about the equation for adding a triangle's exterior angles.
From the figure, we can observe that ∠1, ∠2, and ∠3 are the exterior angles of triangle ABC. We know that the sum of all the exterior angles of any polygon is equal to 360°.
Thus, sum of all the exterior angles of a triangle = 360°
Therefore, In triangle ABC the sum of exterior angles,
∠1 + ∠2 + ∠3 = 360°

What is an equation?
An equation is a formula in mathematics that expresses the equivalence of two expressions by linking them with the equals symbol =. The word equation and its cognates in various languages may have somewhat different definitions; for example, in French, an équation is defined as including one or more variables, but in English, an equation is any well-formed formula consisting of two expressions linked by an equals sign. Solving an equation with variables entails finding which variables' values make the equality true. The variables for which the equation must be solved are also known as unknowns, and the values of the unknowns that fulfill the equality are known as equation solutions. Identity equations and conditional equations are the two types of equations.
The cost function is given by the equation d = 3m + 5

customers arrive at a checkout counter in a department store according to a poisson distribution at an average of seven per hour. what are the probabilities that
From the information given in the Poisson Distribution, the probability that that no more than three customers arrive that is P (X≤3) = 0.0817.
What is a Poisson Distribution?
The Poisson distribution is a discrete probability distribution in probability theory and statistics that articulates the likelihood of a specific number of events happening in a fixed interval of time or space if these events occur with a particular frequency mean rate and regardless of the time since the last event.
What Are the Poisson Distribution's Assumptions?
To be correct, all events must be independent of one another, the pace of occurrences must be steady across time, and events cannot occur concurrently. Furthermore, the mean and the variance will be equal.
What is the justification for the above result?
According to a Poisson distribution, seven people come at a checkout counter in a department store every hour on average. i.e λ=7
Probability (P) that no more than three customers arrive is notated as P(X≤3)
= P(X=0) + P(X=1) + P(X=2) + P(X=3)

What is equation and Quadratic equation?
A statement that shows the equality between two mathematical expressions by connecting the two mathematical expression with an equal to (=) sign is called equation.
A two degree equation is known as quadratic equation.
Let [tex]ax^2+bx +c[/tex] be a quadratic equation (a ≠ 0)

Length of rectangular park = 50m
Breadth of rectangular park = 30m
Area of rectangular park = [tex]50 \times 30[/tex]

Length of rectangular park with safety zone = (x + x + 50) m
= (2x + 50) m
Breadth of rectangular park with safety zone = (x + x + 50) m
= (2x + 30) m
Area of rectangular park with safety zone = (2x + 50)(2x + 30) [tex]m^2[/tex]
= [tex]4x^2 +60x + 100x + 1500[/tex]
= [tex](4x^2 + 160x +1500) m^2[/tex]
Area of safety zone = [tex]4x^2 +160x+1500-1500[/tex]

By the problem,
[tex]4x^2 +160x=1500[/tex]

a + b - 8 = p solve for a
Answer:
a = −b + p + 8
Step-by-step explanation:
a + b - 8 = p solve for a
a + b - 8 = p
subtract b from both sides:
a + b - 8 - b = p - b
a - 8 = p - b
add 8 to both sides:
a - 8 + 8 = p - b + 8
a = p - b + 8
rearrange for alphabetical order:
a = −b + p + 8
Answer:
a = p + 8 - b
Step-by-step explanation:
Step 1: Add 8 both sides
[tex]\displaystyle{a+b-8+8=p+8}\\\\\displaystyle{a+b=p+8}[/tex]
Step 2: Subtract b both sides
[tex]\displaystyle{a+b-b=p+8-b}\\\\\displaystyle{a=p+8-b}[/tex]
Note: You can also subtract b both sides first then add 8 both sides.
Therefore, the new equation when a-term is the subject is [tex]a=8+p-b[/tex].

The distinction among rational numbers as well as fractions is that fractions cannot include a negative denominator or numerator. As a result, the numerator and denominator of the a fraction are all numbers (denominator 0), whereas the numerator and denominator of rational numbers are integers.A rational number, p/q, is considered to be in standard form if its numerator and denominator (p and q) share no common divisor (or factor) other than 1 and its denominator "q" is positive.For the given number-
π, 5/4, -8, 2.35 bar, 19/7, 8, 0
All numbers except π are rational as they are either ending number or have the bar which means they will repeat after some point.
π is the only number which have the value 3.14........and so o such that, it is nether terminating nor repeating.
Thus, π is the irrational number.

So, we want a graph with a closed circle at 2 with the arrow pointing to the right.
Answer:
2nd choice
Step-by-step explanation:
6x - 2 ≥ 10
add 2 to both sides
6x - 2 + 2 ≥ 10 + 2
6x ≥ 12
divided b0th sides by 6 to get x alone
6x/6 ≥ 12/6
x ≥ 2
x is greater than or equal to 2
equal to 2 is shown by a shaded in circle (cannot be option 3 or 4)
x is bigger than 2 so the arrow is to the right
