Answer: The answer is (D) cubic monomial.

Step-by-step explanation: The given polynomial is $5x^3.$

We are to select the correct description of the above polynomial from the given options.

Since there is only one term in the polynomial, so it is a monomial.

Also, the power of the unknown variable is 3, so the degree of the polynomial is 3 and so it is a cubic polynomial.

Therefore, the given polynomial is a cubic monomial.

Thus, (D) is the correct option.

Answer: No, there isn't a proportional relationship.

Step-by-step explanation: In these type of problems, always divide. For it to be proportional, the number of children/ apple slices should be the same for all days. But it isn't, the value differs.

Given 14 – 2(x + 8) = 5x – (3x – 34), prove x = -9 what are the steps to be able to prove x=-9

Veronika [31]

Answer: x = -9

steps

Simplifying

14 + -2(x + 8) = 5x + -1(3x + -34)

Reorder the terms:

14 + -2(8 + x) = 5x + -1(3x + -34)

14 + (8 * -2 + x * -2) = 5x + -1(3x + -34)

14 + (-16 + -2x) = 5x + -1(3x + -34)

Combine like terms: 14 + -16 = -2

-2 + -2x = 5x + -1(3x + -34)

Reorder the terms:

-2 + -2x = 5x + -1(-34 + 3x)

-2 + -2x = 5x + (-34 * -1 + 3x * -1)

-2 + -2x = 5x + (34 + -3x)

Reorder the terms:

-2 + -2x = 34 + 5x + -3x

Combine like terms: 5x + -3x = 2x

-2 + -2x = 34 + 2x

Solving

-2 + -2x = 34 + 2x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-2x' to each side of the equation.

-2 + -2x + -2x = 34 + 2x + -2x

Combine like terms: -2x + -2x = -4x

-2 + -4x = 34 + 2x + -2x

Combine like terms: 2x + -2x = 0

-2 + -4x = 34 + 0

-2 + -4x = 34

Add '2' to each side of the equation.

-2 + 2 + -4x = 34 + 2

Combine like terms: -2 + 2 = 0

0 + -4x = 34 + 2

-4x = 34 + 2

Combine like terms: 34 + 2 = 36

-4x = 36

Divide each side by '-4'.

x = -9

Which statement is true about the circumference of a circle? The circumference is equal to the radius of the circle. The circumf

Irina18 [472]

<h3>The true statement about circumference of a circle is: circumference is found by multiplying Pi by the diameter</h3>

Solution:

The circumference of a circle is given as:

$\text{circumference } = 2 \pi r$

Where,

"r" is the radius of circle

We know that,

$diameter = 2 \times radius\\\\d = 2 \times r\\\\d = 2r$

Thus the circumference can also written as:

$\text{circumference } = 2 \pi r\\\\\text{circumference } = \pi \times d$

Thus, the circumference is found by multiplying Pi by the diameter is correct statement
