B
It’s the only answer that begins with a positive number
Answer: Circle
Step-by-step explanation:
Check the variables' degrees and their coefficients' signs to determine the type of the conic.
Use the formula y2 -y1/x2-x1
Infinity because it's a cubic function with no restricted range or domain
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.
