Two garden plots are to have the same area. One is square and one is rectangular. The rectangular plot is 2 meters wide and 8 me
Crank

First, let's look at the formulas for the area of square and area of the rectangle.

A_{square}=a^2

A_{rectangle}=a\cdot b

And what this exercise states is that the areas are the same. So:

A_{square}=A_{rectangle}\Longrightarrow a^2=a\cdot b

Now put in the data.

a^2=2\cdot8

Solve for a:

a=\sqrt{2\cdot8}=\sqrt{16}=\boxed{4}

The side of the square garden plot is 4 meters.

Hope this helps.

Alessandro wrote the quadratic equation –6 = x2 + 4x – 1 in standard form. What is the value of c in his new equation?
Black_prince [1.1K]

Answer:

5

Step-by-step explanation:

To write it in standard form, we set the equation equal to 0.  To do this, we add 6 to each side:

-6+6 = x² + 4x - 1 + 6

0 = x² + 4x + 5

The related function is

y = x² + 4x + 5

The value of c in this function is 5.
