Which best describes the solution set for the inequality below?

Mathematics

8 0

3x + 7 <_ 4x -8

Subtract 3x from both sides.

3x - 3x = 0x

4x - 3x = 1x (or just x)

7 <_ x -8

Add 8 to both sides.

7 + 8 = 15

-8 + 8 = 0

x _> 15 is the solution for the first inequality.

Although A.) is the only one with x_>15, let's continue to ensure our answer.

-2x + 3 _> 1

Subtract 3 from both sides.

3 - 3 = 0

1 - 3 = -2

-2x _> -2

Divide both sides by -2 to solve for x.

-2x / -2 = x

-2 / -2 = 1

Remember to flip the inequality when dividing or multiplying by a negative.

x <_ 1 is our other inequality.

Our answers are:

x_> 15 and x<_1

____ [38]

Answer:

12x^3+2x

Step-by-step explanation:

The perimeter of a polygon is equal to the sum of its sides.

The sides in the triangle shown have lengths 2x^3+6x, 4x^3-5x, and 6x^3+x in no specific order.

Since its perimeter is given by the sum of its sides, the perimeter is equal to:

2x^3+6x+4x^3-5x+6x^3+x

Combine like terms:

\boxed{12x^3+2x}

Choose the best description for the real number 35
Natalija [7]

Answer:

A) Irrational, because it is not a terminating or repeating decimal.

Step-by-step explanation:

Every time a square root results in a decimal, it will always never end, and never repeat. The square root of 35 qualifies for both of these qualities, therefore, making the answer (A). Hope this helps!
