How many solutions does the system have? Y=-2x-4 y=3x+3

1

Step-by-step explanation:

Since they are not parallel nor the same line, they have 1 intersecting point, which is the solution.

If they were parallel, they would have no solution.

If they were the same line, they would have infinite solutions.

We can find this by finding the perimeter of the square.
31×4= 124
Now the rectangle has two sets of parallel lines. There are two lines that are 22 cm, which comes out to 44 cm. We can subtract 44 from the perimeter to find the total of the length doubled.
124-44
80÷2
40
So, the length of the rectangle is 40 cm.
