Answer:

6(x-10)(x+9)

Step-by-step explanation:

First, make A equal one by factoring out the greatest common factor, 6. This makes the new expression 6(x^{2} +x-90). Then, factor the remaining polynomial by finding two numbers that multiply to -90 and add to 1. These two numbers are -10 and 9. So, add each term to x and then multiply to get the final answer, 6(x-10)(x+9).

What is the value of x in the following equation? -3x-2=2x+8
Arlecino [84]

Answer:

-2 =x

Step-by-step explanation:

-3x-2=2x+8

A sample of students is taken from the school's A honor roll. The school estimates that there are actually 360 students on the A
aliya0001 [1]

Answer:

360 - Y

Step-by-step explanation:

From the information provided in the question, we will understand that the question lacks detailed information.

Given that:

The total number of actual students on the A honor roll = 360

To find the number of students on the A honor roll of 8th graders;

Let denote Y to represent the total number of students who exist on the A honor roll except for the 8th graders.

Then:

The number of 8th graders = all number of students on are on the A honor roll - Y

The number of 8th graders = 360 - Y

If Y is known, then the number of the 8th graders can be fully determined.

Answer:

Option C:   $ \sqrt{\textbf{121}} $

Step-by-step explanation:

Given the side length of a square is 11 units.

Note that $ \sqrt{121} = \pm 11 $

Since, length cannot be negative, we can eliminate - 11.

Hence, the length of the side of the square is 11 units = $ \sqrt{11^2} = \sqrt{121} $.

Hence, the answer.
