Please help with this question... Which expression is equivalent to x^3/2?​

Answers

Answer: D

Step-by-step explanation:

Answer:

Solve (x+2/x-3);(x-2/x-3) Equating the equation to zero and taking out (x-3) as common denominator (x+2)(x-2)/ (x-3)2 Solving using the identities we get => (x2– 4)/(x2 -6x + 9)= 0 => (x2– 4)=(x2-6x + 9) => -4= -6x +9 => -4 -9= -6x => -13= -6x => 13=6x => x= 13/ 6

Find the sum of the measures of the interior angles of a convex 45-gon.​

Answers

Answer: 7740

Step-by-step explanation: take 180(n-45) and n represents the sides

The sum of the measures of the interior angles of a convex 45-gon.​

is 7740.

What is a cube?

It is a polygon having six faces.

The volume of a cube is a side³.

We have,

Polygon with side = 45

Sum of interior angles of any polygon = (n - 2) x 180 ______(1)

Now,

n = 45

So,

Substituting n in (1)

(n - 2) x 180

= (45 - 2) x 180

= 43 x 180

= 7740

Thus,

The sum of the measure of the interior angles is 7740.

Each side of a square sandbox is 36 inches long. What is the area of the sandbox

Answers

Answer: 1296 inches

Explanation:

Given: Side of sandbox = 36 inches
To Find: Area of sandbox
Area of square sandbox = s*s
= 36*36
= 1,296 inch

Hope it helps you...

The area of the square sandbox is 1,296 square inches

What is  area of square?

The area of a square is the measure of the space or surface occupied by it. It is equal to the product of the length of its two sides. Since the area of a square is the product of its two sides, the unit of the area is given in square units.

Area of a square = Side × Side

                            =  [tex]Side ^{2}[/tex]

According to the question

Side of a square sandbox =  36 inches

Therefore,

The area of the square sandbox =  [tex]Side ^{2}[/tex]

                                                      =  [tex](36)^{2}[/tex]

                                                      =  1,296 square inches

Hence, the area of the square sandbox is 1,296 square inches

A construction crew is paving a road. The crew has already paved 1,000 square feet and can pave at a rate of 300 square feet of road per hour. The function f(x) = 300x

Answers

Answer:

Step-by-step explanation:

i go to southwind what’s the answer ??

The crew would spend 3.33 hours to pave a road that is 1,000 ft².

A linear equation is in the form:

y = mx + b;

where y, x are variable, m is the slope of the line and b is the y intercept.

Let f(x) represent the amount of space paved in x hours.

Given the function:

f(x) = 300x

Therefore to pave 1000 ft²:

1000 = 300x

x = 3.33 hours

The crew would spend 3.33 hours to pave a road that is 1,000 ft².

Step-by-step explanation:

This triangle is a special right triangle. In triangles with the angles 30, 60, and 90, the side opposite of the 30 degree angle will always be half the length of the hypotenuse. The hypotenuse is the longest side of a right triangle. In a 30 60 90 triangle, the long side will be equal to the short side multiplied by the squareroot of 3, but that is not needed for this problem. Since the hypotenuse is 12, the side opposite of the 30 degree angle, labeled "s h o r t" will be half of 12. Half of 12 is equal to 6, therefore the short side will be equal to 6.

Write the equation of the line that passes through the points (3, -2)
and (5, -9). Put your answer in fully reduced point-slope form,
unless it is a vertical or horizontal line.

Answers

start with determining the slope ((-9 - (-2))/(5 - 3) = -7/2. Now use the point slope formula y - y1 = m(x - x1). y - (-2) = -7/2(x - 3). Distribute the -7/2, y + 2= -7/2x + 21/2. Combine like terms y = -7/2x + 17/2. You can also write this as y = -3.5x + 8.5
