Answer:

P = 2(4x - 5)

Step-by-step explanation:

The formula for solving the perimeter of a rectangle is:

P = 2(L + W), or

P = 2L + 2W

Given the length (L) = 3x - 7, and width (W) = x + 2:

Substitute these values into the perimeter formula in order to solve for x and determine the actual dimensions of the given rectangle.

P = 2L + 2W

Use the distributive property of multiplications (over subtraction and addition, respectively), and distribute 2 into each parenthesis:

P = 2(3x - 7) + 2(x + 2)

P = 6x - 14 + 2x + 4

Combine like terms:

P = 8x - 10

Factor out the common term to reduce the algebraic expresssion into its simplest form:

P = 2(4x - 5)

Therefore, the perimeter of the given rectangle in its simplest form is:

P = 2(4x - 5).

225% of what number is 81
Airida [17]
To find a percentage of a number we multiply the percentage times the number and get the result, here we have the percentage and the result and need to find out which number it corresponds to, lets write an equation to do so and keep in mind that the percentage itself can be written in a different way:
225% = 225 out of 100 = 225/100
So we have this equation, where we call x the number we are looking for:
<span>(225%)(x) = 81
</span>(225/100)(x) = 81
so we solve for x:
225x = 81*100 = 8100
x = 8100/225
x = 36
The original number is 36, hence 225% of 36 is 81

Answer:

-1 Not in domain

0 In domain

1 In domain

Step-by-step explanation:

The domain for the square root function is all positive numbers including (0). The domain is the set of real numbers which when substituted into the function will produce a real result. While one can substitute a negative number into the square root function and get a result, however, the result will be imaginary. Therefore, the domain for the square root function is all positive numbers. It can simply be expressed with the following inequality:

x\geq0

Therefore, one can state the following about the given numbers. Evaluate if the number is greater than or equal to zero, if it is, then it is a part of the domain;

-1 => less than zero; Not in domain

0 => equal to zero; <em> </em>In domain

1  => greater than zero: In domain

What is f(3)??????????
AURORKA [14]
<h3><u>Explanation</u></h3>
  • Meaning of f(a)

f(a) means the value of f(x) is ... when x = a. That means if we substitute x = 3, we would get f(3).

f(3) also means the value of f(x) is ... when x = 3.

f(x) can also be defined as y // f(x) = y

  • Find f(3) by graph.

You can find the value of f(x) at specific domain from the graph by looking at x = 3 then look up to where the point or where the graph passes. From the graph, when x = 3 as we look up and the graph passes y-coordinate at 1.

Therefore we can say that when x = 3, y = 1.

<h3><u>Answer</u></h3>

f(3) = 1
