Answer:
- x = 375 square feet and y = 6,300 pounds.
Explanation:
The table is:
AIRPLANE LIFTING FORCE
Area of Wings Lifting Force
(square feet) (pounds)
125 1,875
150 2,250
175 2,625
250 3,750
x 5,625
420 y
The ratio of lifting force to the area is equivalent for all pairs in the table. What are the values of x and y?
<u>1. Calculate x:</u>
Ratio of lifting force to the area for the first pair (row):
Ratio of lifting force to area for the pair with x:
Set the proportion:
Equal the two ratios
Multiply both sides by 5,625 (multiplication property of equalities):
<u>2. Calculate y:</u>
You can use the same know ratio for the first pair: 125/1,875
And set the corresponding proportion, with y:
Invert both sides:
Multiply both sides by 420
The answer is x = 375 square feet and y = 6,300 pounds.

Answer:
x = -3, 0, 2
Step-by-step explanation:
=> x³ + x² - 6x = 0
=> x(x² + x - 6) = 0
=> x² + x - 6 = 0 or x = 0
=> x² + 3x - 2x - 6 = 0 or x = 0
=> x(x + 3) - 2(x + 3) = 0 or x = 0
=> (x + 3)(x - 2) = 0 or x = 0
=> x = - 3 or x = 2 or x = 0
