Answer:
a). 3a² + 17a - 1
b). 4y (7y-6)
Step-by-step explanation:
in the second question, we find a number that can divide 28 and 24 without a remainder, which is 4
First, draw a diagram. The datum level would be where the helicopter is at up in the sky. An angle of depressing means that instead of rising, the angle start from the horizontal and moves clockwise. Then, you have the altitude which forms a vertical line opposite to the 18 degrees. You are to find x which is adjacent to the 18 degrees. Since the diagram forms a right angle, you use the tangent function:
tangent 18 = opposite / adjacent
tangent 18 = 1560 / adjacent
adjacent = 4,801.19
Thus, the horizontal distance is 4,801.19 ft

Answer:
Answer : and
Greatest common factor of
If we are able to factor out from each option then that would be our answer.
Lets check with each options
(a), we cannot take out 5.
(b), We can take out common factor and it can be written as
(c) , we cannot take out n^2 because we have only 'n'
(d) , We can take out common factor and it can be written as
(e) , we cannot take out 5 because we have 24
So answer is (b) and (d)
