Answer:
Step-by-step explanation:
The formula for area of a rectange is lw, where l is length and w is width. Since x-4 and 5x+2 are the sides, we can multiply them together to give us the area. We do (x-4)(5x+2). We use the FOIL method (First Outside Inside Last) and get 5x^2-18x-8.
Answer:
Option A
Step-by-step explanation:
Slope of a line passing through two points and
is given by,
Slope =
Line shown in the graph is passing through two points (2, 8000) and (4, 7000).
Therefore, slope of the given line =
= -500 feet per mile
Which means, altitude decreases by 500 ft every mile.
(Negative sign represents the decrease)
Option A is the correct option.
