I'm going to assume that they are on parallel tracks, and not the same track.

60x=40(x+2)

60x=40x+80

20x=80

x=4

You can check the work I've provided by filling in the answer for x into the initial question.

The base of a regular pyramid is a hexagon.
Lyrx [107]
If you think about it, a hexagon can be cut into 6 equilateral triangles. Because of this, all you need to do is find the area of one triangle and multiply it by 6. Since the side length of one triangle is 12, we know that is the base. Since the triangles that are created when cutting the equilateral triangle in half are both 30 60 90, the height must be 6(3)^1/3. We can then multiply 12 • 6 radical 3 •1/2 to get 36 radical 3. Multiply this by 6 and get 216 radical 3 units squared.

7c-11=17 what does c equal. Plz show work. Thanks :D
Gnom [1K]
Since you are subtracting 11 on the side with the variable, you have to add it on the other side. 17+11=28. Then, to solve the problem you are left with, 7c=28. You are multiplying on the side of the variable, so you divide 28 by 7. Your answer to the problem is C=4 i hope this helps

The equation is:
f ( x ) = 4 * 5 ^{2x}
f ( - 1 ) = 4 * 1/25 = 4/25 ( false )
f ( 0 ) = 4 * 1 = 4 ( false )
f ( 1 ) = 4 * 25 = 100 ( false )
f ( 2 ) = 4 * 5 ^4 = 4 * 625 = 2500  ( correct )
Answer:
D )  ( 2,  2500 )
