if the sum interior anhles of a regregrar polygon is equl to 720

find the number of side​

Answer:

34-5x

Step-by-step explanation:

(12+2x-9)-(-15+7x-16)

(3+2x)-(-31+7x)

3+2x+31-7x

34-5x

Answer:

a

Step-by-step explanation:

Every x or domain is unique and doesn't repeat. Therefor, it will pass the vertical line test. You can not have a repeating x.

Answer:

The distance between their tops is 130 feet

Step-by-step explanation:

The given parameters are;

The height of A, [tex]h_A[/tex] = 2 × The height of B - 10

The distance between the two buildings, d = 120 feet

The height of B, [tex]h_B[/tex] = 60 feet

Therefore, we have;

The height of A, [tex]h_A[/tex]  = 2 × The height of B - 10 = 2 × 60 - 10 = 110 feet

The height of A, [tex]h_A[/tex] = 110 feet

By Pythagoras theorem, the distance between their tops = √(([tex]h_A[/tex] - [tex]h_B[/tex])² + d²)

Substituting the values gives;

The distance between their tops = √((110 - 60)² + 120²) = 130

The distance between their tops = 130 feet.

the answer is 138, because you divide first then add and then multiply.

Answer:

138 (if the exponent 3 in strictly on the 5)

5832 (if the exponent 3 in on the whole problem)

Answer:

4.8 x 10^12

Step-by-step explanation:

Move the decimal to the second space so:

4.800000000000

Then count how many spaces the decimal moved so:

12

Then get rid of the 0s and add the x 10^12 so: 4.8 x 10^12.

Step-by-step explanation:

4,800,000,000,000 = 4.8 x 10^12

Answer:

I think it is C I do not know

Answer:

no, it is rational

Step-by-step explanation:

a rational number is one that can be expressed as division of an integer by a nonzero integer. So it is rational, not irrational.

=========================================================

Explanation:

The front triangular face is a triangle with base 8 and height 6. Its area is

A = 0.5*base*height

A = 0.5*8*6

A = 24 square feet

The back triangular face is also 24 square feet since these are the base faces of the prism. The base faces are always congruent. It might help to imagine this figure is turned on its side.

The slanted lateral face is a rectangle of length 10 ft and width 5 ft, so its area is L*W = 10*5 = 50 square feet

The rectangular face on the left is 6 ft by 5 ft giving an area of 6*5 = 30 square feet.

Lastly, the bottom rectangular face is 8 ft by 5 ft giving an area 8*5 = 40 square feet

Overall, the total surface area is: 24+24+50+30+40 = 168 square feet

We just add up all the individual areas of each face to get the total surface area.

Answer:

x = -10

General Formulas and Concepts:

Pre-Algebra

Step-by-step explanation:

Step 1: Define equation

4.5(8 - x) + 36 = 102 - 2.5(3x + 24)

Step 2: Solve for x

Step 3: Check

Plug in x into the original equation to verify it's a solution.

Here we see that 117 does indeed equal to 117.

∴ x = -10 is a solution of the equation.

Answer: 3ab   IF a^b does NOT mean a to the power of b!

I believe you mean  9a²b and 30ab³

If you really mean 9aᵇ and 30ab³,  then the GCF is 3a.

Step-by-step explanation:

the factors of  9 are 3*3  The factors of 30 are 2*3*5.

The only common factor of 9 and 30  is 3

a is a common factor of a and a²

b is a common factor of b and b³

Answer:

The scale of the model is 1 : 244.

Step-by-step explanation:

15 inches = 1.25 feet. (1 inch = 0.0833333 feet)

Hence, the scale is 1.25 : 305 = 1 : 244. (1.25 / 1.25 : 305 / 1.25)
