x+3y=21
12+3y=21
3y=9

For the above figure, the formula is,
x² = WY (YV + WY)
WY = 5
YV = 12
Substituting in the above formula,
x² = 5 x (12 + 5)
x² = 5 x 17 = 85
x² = 85
⇒ x = √85 = 9.21954 = 9.220
Answer:
0.5 seconds
Step-by-step explanation:
Two rockets are launched at the same time, but from different heights.
when the heights are same then y are equal. So equation both equations and solve for t
Add -16t^2 on both sides
Subtract 150 t from both sides
Divide 10 on both sides
t=0.5 seconds
