which figures are polygons

Answers

Answer 1

Polygon: a figure formed by coplanar segments

with one distinct interior region

Figure A, Figure B, and Figure D would be considered polygons.

Notice that those figures I mentioned above are

composed of line segments, and nothing else.

In addition, these figures don't have two separate

interior regions and figures that do aren't polygons.

Figure C would not be a polygon because

it's formed by a curve rather than line segments.

Thanks!

Answers

Answer:

10x + 19

Step-by-step explanation:

The expression 2(5x + 6) can be simplified to 10x + 12, and when that is combined with 7, the result is 10x + 19.

Answer: First, distribute the 2 to the parentheses:

2 * 5x + 2 * 6 + 7 = 10x + 12 + 7

Next, combine like terms:

10x + 12 + 7 = 10x + 19

So the result is 10x + 19.

Based on the figure below, what is the value of x? (5 points)
A right angle is shown divided in two parts. The measure of the angle of one part is 50 degrees and the measure of the other part is 5x plus 15 degrees.
a 5
b 7
c 11
d 15

Answers

Answer: a. 5

Since the angle is right, we know it is equal to 90 degrees.

Using the information provided, we can set up an equation.

50 + 5x + 15 = 90

Simplifying the equation, we get:

5x + 65 = 90

Subtracting 65 from both sides, we get:

5x = 25

Dividing both sides by 5, we get:

x = 5

The length of a building is 60 feet. The length of the building on a scale drawing is 4 inches. Which ratio describes the scale of the drawing?

-- giving brainliest to whoever has the answer (with descriptions and such)
-- if no one else answers (but only one person), i'll be able to give five stars and a thanks

Answers

15-1… or 15:1 because 60 divided by 4 is 15 and 4 divided by 4 is 1

the ratio of the scale drawing is

1 inch on the drawing represents 180 feet in real life.

To determine the ratio of the scale drawing, we need to first find the length of the building on the scale drawing. We know that the actual length of the building is 60 feet, and the length of the building on the scale drawing is 4 inches. We can set up a proportion to find the length of the building on the scale drawing:

Actual length / Length on scale drawing = Scale factor

We can plug in the values we know:

60 feet / Length on scale drawing in inches = Scale factor

To solve for the length on the scale drawing in inches, we can cross-multiply:

60 feet * 1 inch / Scale factor = Length on scale drawing in inches

Simplifying:

Length on scale drawing in inches = 60 feet * 12 inches / Scale factor

We know that the length on the scale drawing is 4 inches, so we can plug that into the equation:

4 inches = 60 feet * 12 inches / Scale factor

Solving for the scale factor:

Scale factor = 60 feet * 12 inches / 4 inches

Scale factor = 180

What is the value of x?

Enter your answer in the box.
Two intersecting lines. The angle formed at the top is labeled 3 x plus 50 degrees. The angle formed at the bottom directly opposite it is labeled 6 x minus 10 degrees.

Answers

We know that the two angles are opposite and therefore are equal, so we can set them equal to each other and solve for x:

3x + 50 = 6x - 10

Adding 10 to both sides, we get:

3x + 60 = 6x

Subtracting 3x from both sides, we get:

60 = 3x

Dividing both sides by 3, we get:

x = 20

Therefore, the value of x is 20.

I need help on a b and function 2
I dont get it

Answers

Answer:

For A: The first function has a greater ROC

For B: The first function has a negative slope

Step-by-step explanation:

Explication for A:

We already know that the R.O.C. (slope) is 2 for the first function, so all we need to do is substitute the values in the table into the following formula: y2-y1/x2-x1

after substituting: (-3-(-6))/(0-(-1))

simplify 3/1=3, since the ROC is 3, the second equation has a greater ROC than the first

Explanation for B:

The first function described is f(x)=20-3.5x

This is because the y intercept is the starting point, or how much money she has in the gift card. She spends 3.5 dollars per week, so we add a variable to represent the number of weeks, and its negative since she is spending, not earning. We also know that the slope is negative since y is decreasing as x is increasing, on the table.

The second function described is c(m)=5x+10

This is because the equation represents the total cost of renting a calculator, so both terms are positive.

Answer: $x=3$

Step-by-step explanation:

STEPS FOR SOLVING LINEAR EQUATION

$20-2(x=5)=24$

Use the distributive property to multiply −2 by x−5.

$20-2x+10=24$

Add 20 and 10 to get 30.

$30-2x=24$

Subtract 30 from both sides.

$-2x=24-30$

Subtract 30 from 24 to get −6.

$-2x=-6$

Divide both sides by −2.

$x=\frac{-6}{-2}$

Divide −6 by −2 to get 3.

$x=3$

Use the distributive property to find the equivalent expression.

Angles in a triangle = 180°.

117 - 90 = 27

So X is 27 degrees

Answer:

27°

Step-by-step explanation:

The sum of angles in a triangle is 180°

We see that there is a right angle and an angle that measures 63°

To find the missing angle, we just add 90+63 and then subtract that from 180

90+63= 153

And then subtract that from 180

180-153=27°
