Which equation can you use to solve this problem?

you are 412412 feet tall.
you must be 55 feet tall to ride on a roller coaster.
how much more do you need to grow in order to ride the roller coaster?

a 5 +5 + amount you need to grow =412=412

b amount you need to grow =412+5=412+5

c 5−92=5-92= amount you need to grow

d 52−42=52-42= amount you need to grow

since the airplane is moving with constant speed then the distance travelled can be calculated by x=u*t

in km/h would be:

x=640*3.5=2.240 km

in m/s would be:

u=640 km/h= 640.000 m/h =640.000/ 3600 m/s =177.8 m/s

t= 3.5 h= 3.5 * 3600 s=12.600 s

then x=u*t= 177.8*12.600= 2.240.280 m

18

step-by-step explanation:

draw the shape and you will see that f and k are actually at adjacent vertices (points of the hexagon that are neighboring).   so find the distance between (1,2) and (4,2).   that is easy since (1,2) and (4,2) is just a vertical distance to count, which is 3.   it is a regular polygon which means all sides are congruent.   you have 6 sides (hexa) so multiply 6 by 3 to receive 18.
