thats the problem the words say. Write an expression in simplest form that represents the perimeter of the polygon
Answer:
(29x + 9)
Step-by-step explanation:
Perimeter of a polygon = Sum of measures of all sides of the polygon
Therefore, Perimeter of the given polygon = (9 + 12x + 2x + 2x + 12x + x)
= (9 + 29x)
Expression (29x + 9) will represent the perimeter of the polygon.

Answer:
y = ⅓x - 3
Step-by-step explanation:
First, find the slope using two points on the line, say (0, -3) and (6, 0):
[tex] \frac{y_2 - y_1}{x_2 - x_1} = \frac{0 - (-3)}{6 - 0} = \frac{3}{6} = \frac{1}{3} [/tex]
Slope (m) = ⅓
Find the y-intercept (b):
The line intercepts the y-axis at y = -3. So b = -3
Next, substitute m = ⅓ and b = -3 into y = mx + b (slope-intercept form):
y = ⅓(x) + (-3)
y = ⅓x - 3

by the Angle sum property of triangle,
55+75+(-6+7x) = 180
=> 130 +(-6+7x) = 180
=> (-6+7x) = 180-130
=> (-6+7x) = 50
=> 7x = 50+6
=> 7x = 56
=> x= 56/7
=> x = 8

Answer:
Volume of the prism = 280 ft^3
Step-by-step explanation:
Recall that the volume of a prism is given by the following formula:
Volume = B * H
where B is the area of the base (in our case a right angle triangle), and H is the prism's height (in our case 16 ft)
Then we estimate the area of the triangle at the base as base* height/2 :
Area triangle = 5 * 7 / 2 = 35/2 ft^2
and multiply by the prism's height to get its volume:
Volume = 35/2 * 16 = 280 ft^3

60% of what number is 348?
Answer:
208
Step-by-step explanation:
this is what I did. 348×.6
60% of 580 is 348 is the answer you're looking for
If you divide .6 by 348 you get 580.
To check your answer, you can do .4 (40%) multiplied by 580 to get 232
232+348=250 which is 100%

I want to double-check my answer. I think it may be wrong. I need this ASAP. Have a great day.
This is not the correct answer.
1. 2.30 is not even close to the point given in the number line.
2. My guess for the correct answer would be 0.23 because in between 0.2 and 0.3 is 0.25, so the best answer would be 0.23.

Identify the variable in the algebraic expression.
5x + 13
Answer:
x
Step-by-step explanation:
The definition of a variable is an unknown quantity, usually represented by a letter.
The variable in the algebraic expression 5x + 13 will be 'x'.
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
The algebraic expression is,
⇒ 5x + 13
Now,
Since, The algebraic expression is,
⇒ 5x + 13
Hence, The variable of the algebraic expression = x
Therefore, The variable in the algebraic expression 5x + 13 = x

Which angle is vertical to
(Will reward)
The area of the right-
angled triangle is
equal to the area of
the rectangle.
Work out the value of
x.
Answer:
x = 15 cm
Step-by-step explanation:
Triangle area:
[tex] area = \frac{(20)(15)}{2} = \frac{300}{2} = 150 \: cm[/tex]
Then rectangle area:
[tex]area = (10)(x) \\ 150 = 10x \\ x = \frac{150}{10} \\ x = 15 \: cm[/tex]
Need help #3. The answer is shown, but I don’t know how to get to the answer. Please teach and show steps.
Answer:
A
Step-by-step explanation:
We are given a right triangle with a base of x feet and a height of h feet, where x is constant and h changes with respect to time t.
The angle in radians is defined by:
[tex]\displaystyle \tan(\theta)=\frac{h}{x}[/tex]
And we want to find the relationship that describes dθ/dt and dh/dt.
So, we will differentiate both sides with respect to t where x is a constant:
[tex]\displaystyle \frac{d}{dt}[\tan(\theta)]=\frac{d}{dt}\Big[\frac{h}{x}\Big][/tex]
Differentiate. Apply the chain rule on the left. Again, remember that x is just a constant, so we can move it outside the derivative operator. Therefore:
[tex]\displaystyle \sec^2(\theta)\frac{d\theta}{dt}=\frac{1}{x}\frac{dh}{dt}[/tex]
Since we know that tan(θ)=h/x, h is the opposite side of our triangle and x is the adjacent. Therefore, by the Pythagorean Theorem, our hypotenuse will be:
[tex]\text{Hypotenuse}=\sqrt{h^2+x^2}[/tex]
Since secant is the ratio of the hypotenuse to adjacent:
[tex]\displaystyle \sec(\theta)=\frac{\sqrt{h^2+x^2}}{x}[/tex]
So:
[tex]\displaystyle \sec^2(\theta)=\frac{x^2+h^2}{x^2}[/tex]
By substitution, we have:
[tex]\displaystyle \Big(\frac{x^2+h^2}{x^2}\Big)\frac{d\theta}{dt}=\frac{1}{x}\frac{dh}{dt}[/tex]
By multiplying both sides by the reciprocal of the term on the left:
[tex]\displaystyle \frac{d\theta}{dt}=\frac{1}{x}\Big(\frac{x^2}{x^2+h^2}\Big)\frac{dh}{dt}[/tex]
Therefore:
[tex]\displaystyle \frac{d\theta}{dt}=\frac{x}{x^2+h^2}\frac{dh}{dt}[/tex]
Our answer is A.
