Find the square root of the area and yiull get the answer
N76 [4]3 years ago
4 0

Since each one is a square, each side has to be the same length. I know that 12×12 is 144, so for the first square, each side is 12 inches. Then, use the formula to determine the perimeter. 4×12=48, so the first perimeter is 48 inches. For the second, I know that 9×9=81, so each side is 9. 4×9=36, so the perimeter is 36. For the last, each side is 18 inches. 4×18=72, so the perimeter is 72 inches.

Help please I dont understand this​
s2008m [1.1K]

Answer:

x=6

Step-by-step explanation:

The lengths of line segments \overline{AB} and \overline{AC} because of the two segments and two angles marked as equal in the diagram. Because of this, the arcs \widehat{AB} and \widehat{AC} are equal.

Since there are 360 degrees in a circle, we can now set up the following equation:

(10x-23)+(10x-23)+106=180,\\20x-46+106=180,\\20x+60=180,\\20x=120,\\x=\boxed{6}

Identify the equation in slope-intercept form for the line containing the point (2,1) and parallel to y=5/3x−1/3.
Gekata [30.6K]

Answer:

y = 5/3x -7/3

Step-by-step explanation:

parallel lines will have the same slope

m = 5/3, point (2, 1)

use point-slope form to find the new equation for the parallel line

y - 1 = 5/3(x - 2)

y = 5/3x - 10/3 + 1

y = 5/3x -7/3

This, she says, means you can decrease how much you pay in the long run by saving on interest
