Answer:
10*0.11515
Step-by-step explanation:

Since this can't happen, let's suppose that P=150, then:

Now we have to move the 100 to the other side of the equation with a negative sign to get this:

Finally, to get w, we move the 2 that's multiplying to the other side dividing the 50:

Therefore, the width of the rectangle would be 25 ft if the perimeter is 150ft, and we can see how the rectangle would look:
Answer:

Step-by-step explanation:
Since the vertex is right between the vertex and the directrix, the y value of the vertex must be (3+(-1))/2=1. The x coordinate will just be the same as that of the focus, or in this case 0. This means that the vertex will be at (0,1). Since the graph opens toward the focus, it will be opening up, and since its vertex is at (0,1), it will have an equation of:

Answer:
135
Step-by-step explanation:
A=1/2(b•h) so,
18x15=270
270/2 =135
The sum exterior angles of a square are:
4*90=360°
