M equals 3x+21 because you add 2x+1x=3x.then you add 14+7=21.then you combine them together to get 3x+21
My day was good lol thanks for askinggg
Step-by-step explanation:
Let A(x) be the area function of given rectangle.
Radius of circle = 7x
Therefore, length of rectangle = 14x
Width of rectangle = 7x

Let P(x) be the Perimeter function of given rectangle.

Trick question — it’s a right triangle. Here’s why:
23 + 67 = 90. All triangles have an interior angle sum of 180. 180 - 90 = 90. 90 degrees is right, and therefore, having a right angle, this is a right triangle.
