Answer:

6

Step-by-step explanation:

3n means you are multiplying 3 and n. since n = 2, the only thing you need to do is plug in 2 for n and then simplify by multiplying 3 · 2.

<u>plug in 2 for n:</u>

3n ⇒ 3(2)

<u>multiply 3(2):</u>

3(2) = 6

therefore, when n = 2, 3n = 6.

<h3>What is defined as the term interval notations?</h3>
  • An interval is represented on a number line using interval notation. In all other sayings, it is a method of writing real number line subsets.
  • An interval is made up of numbers that fall between two specific data set.
  • Intervals can be categorized according to the numbers in the set.
  1. Interval Open: The endpoints of a inequality are not included in this type of interval.
  2. Interval Closure; The endpoints of a inequality are included in this type of interval.
  3. Interval with Half-Open Doors: This interval contains only one of inequality's endpoints.

The given interval notation is;

(-3,1], it is the case of half open half close.

-3 comes with the open interval, it means its value will not be included in the interval.

1 is with the closed interval, it means its value will be included in the interval.

Thus, the values lying between the interval (-3, 1] are  -2, -1, 0, and 1.

One side of a rectangle is 3 m more than the other. If the perimeter of the rectangle is 30 m, what are its dimensions? *
uranmaximum [27]

Answer:

the length— 6

width— is 9

Step-by-step explanation:

you said One side— 3m MORE

so we will consider the length Number as X

we will consider width As three plus X

- You want to know the Perimeter. So we have to

add.

— so the expression is 3+3+x+x+x+x = 30

it is then simplified to 6+4x= 30

then we should be able to find out the X  which is 6

when we substitute the values with dimensions, you will get

your final Answer

I hope This Helped!

G(x)=-x^2-1-2x<br> f(x)=x+5<br> Find (g-f)(x)
nikitadnepr [17]

(g-f)(x) is x² - 3x - 6

<u>Step-by-step explanation:</u>

Step 1:

Given g(x) = x² - 1 - 2x, f(x) = x + 5. Find (g-f)(x)

(g-f)(x) = x² - 2x - 1 - (x + 5) = x² - 2x - 1 - x - 5 = x² - 3x - 6
