You can make 6 different towers. If red was at the bottom, there'd be two different possibilities for that: red, yellow, blue, and red, blue, yellow. Same for if blue was at the bottom: blue, red, yellow, and blue, yellow, red. Yellow also applies: yellow, red, blue, and yellow, blue, red. 3*2=6, so 6 possible towers.
If by "coincide", in other words this is also known as intersect, it means that the solution to the system is that intersection point. For instance, if the intersection point of the 2 lines is (5,7) on the graph, it means that in both equations, x = 5 and y = 7. If you mean that the 2 equations result in the same line, it means that the 2 equations were really equal, but that one could be basic to be identical with the other. For example, if you have 2x + 2y = 8 and 4x + 4y = 16, they will give you the same line, and you can see that if you divide that second equation by 2 all the way crossways, it merely shows the first equation.
Answer:
30 ft. x 55ft
Step-by-step explanation:
3 x 5.5
1 inch = 10 ft
3 * 10 = 30
5.5 = 55
30' x 55'
Answer:
answer for a,b and c are all zero (0).
reasons for all:
zero(0) divided by any number is zero(0).
? can be any number except for 3 or -2 as it is already used in (3,4), (-2,-5)
