F(-3) = -2(-3)^2 - 5(-3) + 4 = -2(9) + 15 + 4 = -18 + 19 = 1
The answer is: [C]: " (x - 4) " .

Answer:
The width must be greater than 3 meters.
Step-by-step explanation:
Let w represent the width. Then 5w will represent the length, which is 5 times the width. The perimeter is the total of the side lengths of the rectangle, so is ...
P = 2w + 2(5w) = 12w
We want this to be greater than 36 m, so ...
P > 36 m
12w > 36 m . . . . . . . substitute our expression for P
w > 3 m . . . . . . . . . . divide by 12
The possible values for width are those values that are more than 3 meters.

Answer:
77.6
Step-by-step explanation:
The ratio of light times will be the ratio of distances:
(light time to Neptune) / (light time to Mercury)
= (Neptune distance)/(Mercury distance)
= (27.93×10^8 mi)/(0.3598×10^8 mi) = 27.93/0.3598
≈ 77.6
It takes about 77.6 times as long for light to reach Neptune as it does to reach Mercury.
