Why can you not combine the 8a2 and 8a?

Answers

Answer 1

Answer:

you can't add or subtract numbers that don't have the same variable or the same exponent

Answer 2

Answer:

You cannot combine the terms [tex]8a^2[/tex] and [tex]8a[/tex] because they are not like terms, which are terms that consist of both the same power, and the same variable. Seen with the two terms given, they both share the same variable ([tex]a[/tex]), but not the same power ([tex]2[/tex]).

If the common differences of an Ap is 5, the value of a18-a13 is

Answers

Answer:

25

Step-by-step explanation:

The n th term of an AP is

[tex]a_{n}[/tex] = a₁ + (n- 1)d

where a₁ is the first term and d the common difference

Here d = 5, then

a₁₈ = a₁ + 17d = a₁ + 85

a₁₃ = a₁ + 12d = a₁ + 60

Thus

a₁₈ - a₁₃

= a₁ + 85 - a₁ - 60

= 25

Answer:

In geometry, a polygon is a plane figure that is described by a finite number of straight line segments connected to form a closed polygonal chain or polygonal circuit. The solid plane region, the bounding circuit, or the two together, may be called a polygon.

The segments of a polygonal circuit are called its edges or sides, and the points where two edges meet are the polygon's vertices(singular: vertex) or corners.

So, if a shape has points where two edges meet, it is indeed a polygon. Some examples include: Equilateral Triangles, Squares, Regular Pentagons, Regular Hexagons, Regular Heptagons, and Regular Octagons.

(1) a closed shape in the plane, (2) the sides of a polygon are line segments, and (3) the sides of a polygon meet only at endpoints

Which set of side lengths represents a triangle with 3 lines of reflectional symmetry?
3, 4, 5

Answers

Answer:

5, 5, 5

Step-by-step explanation:

i saw it on quizlet

The set of side length that represents a triangle with 3 lines of reflectional symmetry is 5,5,5

Reflectional symmetry is a line that divides a triangle into halves. The halves the triangle are divided into are a reflection of each other.

A triangle is a shape that has three sides with three angles which sum up to 180 degrees.

Types of triangles :

Equilateral triangle : the three sides of the triangle have an equal length. It has three lines of reflectional symmetry  Right-angled triangle :  the square of the longest side is equal to the sum of the square of the other two sides Scalene triangle : all the three sides of the triangle have different lengths. It has no line of reflectional symmetry. Isosceles triangle ; it has two sides that have an equal length. It has one line of reflectional symmetry

The proceeds from a car wash are directly proportional to the number of cars washed. The total after 9 cars was $180. How much can be raised if 60 cars
are washed?
60 cars washed?

Answers

Answer:

$1200

Step-by-step explanation:

180 divided by 9 is 20, so they earned $20 per car washed. They want to wash 60 cars, and if they wash 60 cars they would earn $1200. (60 x 20)

Answer:

$1200

Step-by-step explanation:

Our revenue is directly proportional to the number of cars. That means our revenue is increasing at a constant rate, and thus, we are getting the same amount of money per car. That means we can find out how much we get from washing 1 car.

[tex]\frac{180}{9} = 20[/tex]

$20 per car.

If we washed 60 cars, we'd earn 60 * $20:

[tex]60*20 = 1200[/tex]

Answer:

Step-by-step explanation:

For a relation to be a function each value of x on the domain can only map to one unique value of y in the range.

For the given point, we can see that

x = 1 → y = 4 and x = 1 → y = 1

This breaks the function rule, thus the set is not a function

Explanation:

The list of first numbers of the ordered pairs is ...

  1, 3, 1, 9, 0.

There is a repeated value, 1, so the relation cannot be a function. Each domain value can only appear once in a relation that is a function.
