Answer:
L=7.94 feet, W=9.88 feet
Step-by-step explanation:
perimeter=78 feet
LxW=78
2L-6=W
substitute
Lx(2L-6)=78
2L^2-6L=78
2L^2-6L-78=0
factor
(2L-15.86)(L+4.95)=0
2L=15.88, L=7.94
L=-7.94 feet
Answer:
49.2
9
Step-by-step explanation:
7.46² - 2.54² = (7.46 - 2.54)(7.46 + 2.54)
= (4.92)(10)
= 49.2
(1 x 4) x 3 = [1² + √(1 x 4)] x 3 = [1 + √4] x 3 = [1 + 2] x 3 = 3 x 3 = 9
Answer: no
Step-by-step explanation:
His return on investment (ROI) is based solely on money from his pocket.
If the profit is x dollars, the ROI is x/20000. Here Dave levered 10:1 with the help of his father.
If he had invested totally with his own money, the ROI would be x/200000, a much less impressive number even though the profit is the same.
