Draw your own rectangle, with an area of 24 square units, on the coordinate plane. Then, identify the vertices of your rectangle
Gnoma [55]

Answer:

First you should remember that the formula for calculating area of a rectangle is;

Area=Length × width

You can decide to have a rectangle with different dimensions provided the area is 24 square unit

For this case, lets choose a rectangle with vertices at (1,0), (7,0),(1,4), (7,4)

After plotting these coordinates, you will notice your rectangle has a length of 6 units and a width of 4 units

A single unit is 1 square unit.When you Count the number of units inside the rectangle formed you realize you have 24 units covered inside

The area of the 24 units will be;

24×1 square unit= 24 square units

Write 14/√2 + √50 in the form b√2 where b is an integer.
kifflom [539]

Answer:

12 \sqrt{2}

Step-by-step explanation:

Taking the terms one at a time,

\frac{14}{ \sqrt{2} }  \\   \frac{14 *  \sqrt{2} }{ \sqrt{2} *  \sqrt{2}  }  \\   \frac{14  \sqrt{2} }{2}  \\  7 \sqrt{2}

\sqrt{50} \\  \sqrt{25 * 2} \\  \sqrt{25}*  \sqrt{2}    \\ 5 *  \sqrt{2}   \\ 5 \sqrt{2}

Adding the terms, you have;

7 \sqrt{2} + 5 \sqrt{2} =(7 + 5) \sqrt{2} = 12 \sqrt{2}

Hope it helps!

What equation(s) represent joint variations? check all that apply c=2pi z=3x/y y=3x+2 w=abc/4 v=lwh
Alinara [238K]

Answer:

Step-by-step explanation:

Joint variations occurs when one variable depends on the value of two or more variables. The variable varies directly or indirectly with the other variables combined together. The other variables are held constant. From the given examples, the equation(s) that represent joint variations are

1) z = 3x/y

z varies directly with x and inversely with y.

2) w = abc/4

w varies inversely with a,b and c. 4 is the value of the constant of variation.
