The area of a square is equivalent to the area of a rectangle. If the side lengths of the rectangular three units and 12 units w
labwork [276]

Answer:

Step-by-step explanation:

If the side lengths of the rectangle are 3 and 12, then the area, length times width, is 36.

If the area of the square is equivalent to the area of the rectangle, then

36=s^2 which is the formula for the area of a square.  Take the square root of 36 to get that each side of the square is 6 inches long.  

Since a square has 4 sides, we get that the perimeter of that square is 4 * 6 which is 24 inches.

Sati [7]

Answer:

<em>y = - </em>\frac{4}{5}<em> x + </em>\frac{44}{5}<em> </em>

Step-by-step explanation:

(6, 4)

(1, 8)

m = \frac{8-4}{1-6} = - \frac{4}{5}

y - 4 = - \frac{4}{5} ( x - 6 )

<em>y = - </em>\frac{4}{5}<em> x + </em>\frac{44}{5} ⇔ y = - 0.8x + 8.8

On a piece of paper, graph y≥ x - 1. Then determine which answer choice
zhannawk [14.2K]

Based on the given inequality of y≥ x - 1, the graph that matches it best is C. Graph A.

<h3>How are inequalities graphed?</h3>

When graphing an inequality with the "greater or equal" and "less or equal" signs, the line will be a steady line as shown by graphs A and B.

If y is the larger or equal variable, the shaded area will be to the left of the line.

The inequality is y≥ x - 1 which means that the line should be steady and the shading should be on the left of the line. Graph A is therefore the correct graph.
