Alex has a grid in the shape of a rectangle. he has right triangles. each right triangle has an area of 25 square millimeters an
Maurinko [17]
First you have to find the area of the rectangular grid. The area of a rectangle is length•width.
So:
A= 20•12
A= 240cm
Then you need to convert 240cm into mm.
240cm is 2400mm.

Then you need to figure out how many triangles can fit into the rectangle if all the triangles have an area of 25mm. So you divide 2400 by 25.
2400:25= 96

So Alex can fit 96 triangles into the grid.

Two nonvertical lines have slopes m 1 and m 2​, respectively. The lines are parallel if​ _______ and the​ _______ are​ unequal;
kondor19780726 [428]

we know that

If two lines are parallel, then their slopes are the same

m1=m2

and the y-intercept is unequal

If two lines are perpendicular, then the product of their slopes is equal to -1

m1*m2=-1  or m1=-1/m2

therefore

<u>the answer is</u>

Two non vertical lines have slopes m1 and m2​, respectively. The lines are parallel if​ m1=m2 and the ​y-intercept are​ unequal; the lines are perpendicular if​ m1*m2=-1 or​ m1=-1/m2.
