Answer:
2x - 7y + 17
Step-by-step explanation:
Subtracting the 2 expressions
2x - 4y + 6 - (3y - 11) ← distribute parenthesis by - 1 )
= 2x - 4y + 6 - 3y + 11 ← collect like terms
= 2x - 7y + 17
45 cars=454
Divide 45 on both sides to get the average length of a single car
1 car = 10.01 ft
Answer:
the height of the taller building is 14.47 m
Step-by-step explanation:
Given the data in the question as illustrated in the image below.
form the image; ( Triangle BDE )
we know that sin∅ i= opposite/hypotenuse
so; sin12° = BE / 21.5
BE = 21.5sin12°
BE = 4.47 m
since, EA = DC = 10 m
BA = BE + EA
BA = 4.47 m + 10 m
BA = 14.47 m
Therefore, the height of the taller building is 14.47 m
