solve this word problem leading to quadratic equation: the area of a rectangle is 60cm². The length is 11cm more than the width.

morpeh [17]

Answer:

Step-by-step explanation:

let : x The length and y the width you have this system :

xy =60....(1)

x = y+10...(2)

put the value for x in (1): (y+10)y =60

the quadratic equation is : y² +10y - 60 = 0

Δ =b² - 4ac a = 1 b= 10 c= - 60

Δ =10² - 4(1)(-60) = 324 =18²

y 1 = (-10-18)/2 negatif...... refused

y 2 = (-10+18)/2 =4

the width is 4

dan and cheryl paddled their canoe 40 mi in 5 hr with the current and 16 mi in 8 hr against the current. Find the speed of the c

Arada [10]

Let the speed of the current be x and the speed of the canoe in still water be y, then

$y+x= \frac{40}{5} =8 \\ y-x= \frac{16}{8} =2$

Adding the two equations, we have:

$2y=10 \\ \\ \Rightarrow y=5$

From any of the equations, we have that x = 2

Therefore, the speed of the current is 2 miles per hour while the speed of the canoe in still water is 5 miles per hour.
