15. Which of the followings represents the sum of four consecutive odd integers? a. x + (x + 1) + (x + 2) + (x + 3)
b. x + (x + 1) + (x + 3) + (x + 5)
O c. x + (x + 2) + (x + 3) + (x + 4)
d. x + (x + 2) + (x + 4) + (x+6)

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

the answer is 0.071

good luck! : d

answer rather than having to add and subtract the measurements of the semi-circle, notice that the semicircle to the left of ad is actually identical in area to the blank semicircle-shaped space to the left of bc. so if we transferred the red semicircle into the blank space, we would end up with a square of side length 24 cm. the area of a square is s^2 = 24^2 = 676 cm^2.

u also answered this so i think u would know but i am here to

put in or use mine
