A rectangle measures 8/3 inches by 9/4 inches. What is its area?

Answers

Answer:

To find the area, you have to multiply the length times the width

Step-by-step explanation:

Answer:

The area of this rectangle is 6 square units.

Step-by-step explanation:

Multiply the width (8/3 inches) by the height (9/4 inches) to get the rectangle area:

 8       9

----- * -----

  3      4

                        8 * 9

This results in ----------    which itself reduces to 6.  

                          4 * 3

The area of this rectangle is 6.

Step-by-step explanation:

In picture

The area of the rectangular portion of the window can be represented by the function A(x) = 2x^2 + 10x. The area of the trapezoidal portion can be represented by the function A(t) = 6((x + 15) + (2x + 10)/2). Formulate a function A(w) that can be used to represent the area of the entire window.

A(w) = 9x + 75

A(w) = x(2x + 10)

A(w) = 21x^2 + 75x

A(w) = 2x^2 + 19x + 75​

Answers

x(2x + 10) is correct because of how it explained up there.

The function A(w) that can be used to represent the area of the entire window is 2x^2+17x+95.

We have given that,

The area of the rectangular portion of the window can be represented by the function A(x) = 2x^2 + 10x.

The area of the trapezoidal portion can be represented by the function A(t) = 6((x + 15) + (2x + 10)/2).

A(t)=6x+90+x+5

A(t)=7x+95

What is the area of the formula?

[tex]Area\ of \ the\ rectangle=Length \times width[/tex]

Therefore the function A(w) that can be used to represent the area of the entire window is

A(W)=A(t)+A(x)

A(W)=7x+95+2x^2 + 10x

A(W)=2x^2+17x+95

The function A(w) that can be used to represent the area of the entire window is 2x^2+17x+95.

If -10x – 9y = -7 is a true equation, what would be the value of
-30x – 27y?

Answers

Answer:

-30x-27y = -21

Step-by-step explanation:

We know that;

-30x-27y = 3(-10x-9y)

Recall, -10x-9y = -7

Thus; -30x-27y = 3(-7) = -21

pls add explanation if possible

Answers

Answer:

Both are rational.

Step-by-step explanation:

As a rational number can be written in the form p/q where p,q are co-prime integers, let a=p1/q1 b=p2/q2.

And we know the product of two integers is an integer

p1q2, p2q1 are integers. And the sum or difference of two integers is rational, rather being specific, it is an integer.

Thus a+b and a-b is rational.

Step-by-step explanation:

Step 1: Set Up System of Equations

[tex]a + b = 13[/tex]

[tex]ab = 40[/tex]

Solve for a in the first equation

[tex]a = 13 - b[/tex]

Subsitur that in for the 2nd equation
