Step-by-step explanation:

Answer 2

Answer:

Answer:

well it depends on what the other/old shape is are they congruent? parallel? you should probably have another shape with measurements to find the area.

Factor the following polynomial completely.

1,280x^11 - 405x^7

Answers

Answer:

$5x^7(16x^2+9)(16x^2-9)$

Step-by-step explanation:

we have

$1,280x^(11)-405x^(7)$

we know that

$1,280=(2^8)(5)$

$405=(3^4)(5)$

substitute

$(2^8)(5)x^(11)-(3^4)(5)x^(7)$

Factor 5x^7

$5x^7[(2^8)x^(4)-(3^4)]$

$5x^7[256x^(4)-81]$

Applying difference of square

$[256x^(4)-81]=(16x^2+9)(16x^2-9)$

substitute

$5x^7(16x^2+9)(16x^2-9)$

Choose some numbers to compare to 55 use = and <,>

Answers

Answer:

The answer in the procedure

Step-by-step explanation:

The numbers are $30,55,80$

Compare the numbers with $55$

a) we know that

$30 < 55$ -----> the number is less than $55$

b) we know that

$55 = 55$ -----> the number is equal to $55$

c) we know that

$80>55$ -----> the number is greater than $55$

50 55 and 60, that is the easiest answer that i could think of

The area of the polygon is 48 mi2. What is the length of side a? miles

Answers

Answer:

Length of side a = 4.30 miles

Incomplete question:

The area of the regular polygon is 48 mi2. What is the length of side a? miles

Step-by-step explanation:

The number of sides of sides of the polygon is not given, so we will assume the polygon is an hexagon as shown in the attached image;

Given;

Area = 48 mi^2

Area of an hexagon using side a can be written as;

A = (3/2)√3×a^2

Making a the subject of formula

a = √(2/3√3 ×A)

Substituting the values

a = √(2/3√3 ×48)

a = √(32/√3)

a = 4.30 miles

To find the Length of Polygon Sides ('a') of a square polygon with an area of 48 mi², we apply the formula a = √Area. This gives a = √48 miles. This formula applies specifically to squares.

Given the area of the polygon is 48 square miles, to find the length of a side, we would first need to know the type of polygon.

For instance, if it's a square, the area is calculated by squaring one of its sides (Area = side²).

Here, to find the side length ('a'), we take the square root of the area. So, a = √Area.

Applying this to the given area, a = √48 miles.

However, please note that this formula is for a square.

Other polygons have different formulas for calculating such dimensions.

Which partial quotients could be added to find 396 ➗ 12? A 20 and 8
B 20 and 4
C 30 and 3
D 30 and 8

Answers

The partialquotient of 396 ÷ 12 is 30 and 3.

What is an expression?

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

396 ÷ 12

12 x 33 = 396

33 is the quotient.

A partial quotient of 33 can be.

30 and 3.

Thus,

30 and 3 are the partialquotient.
