Answer: w = 1/2 and w = -4

Step-by-step explanation:

2w^2+7w-4=0

The quadratic formula is (-b+ - √b^2-4ac)/2a

In this case a=2, b=7, c= -4

(-7+ - √7^2 - 4(2)(-4))/2(2)

(-7+ - √49+32)/4

(-7+ - √81)/4

(-7+9)/4 and (-7-9)/4

2/4 and -16/4

1/2 and -4

A bird leaves its nest and travels 12 miles per hour downwind for x hours. On the return trip, the bird travels 2 miles per hour

aalyn [17]

12x = 10x + 3

Subtract 10x from both sides

2x = 3
Divide by two on each side

x = 3/2 or 1 1/2 hours

Distance of the trip:

12 * 2 * 3/2 = 36 miles

How long does the trip take:

3/2 + 3/2 + 3/10 = 3 3/10 hours
