Solve for x: 2xsquared+4x-16=0

sergejj [24]

2x² + 4x - 16 = 0
2(x²) + 2(2x) - 2(8) = 0
 2(x² + 2x - 8) = 0
 2 2
 x² + 2x - 8 = 0
 x = -(2) ± √((2)² - 4(1)(-8))
 2(1)
 x = -2 ± √(4 + 32)
 2
 x = -2 ± √(36)
 2
 x = -2 ± 6
 2
 x = -1 ± 3
 x = -1 + 3 U x = -1 - 3
 x = 2 x = -4

Raven can walk 2 2/5 miles in 3/5 hour. At this rate, how far can she walk in 1 hour? You might want to change 2 2/5 to an impro

elena55 [62]

The distance traveled by Raven in 1 hour at the given rate is 4.0 miles.

The given parameters:

Distance traveled by Raven = 2 2/5 miles
Time of motion, t = 3/5 hour

The speed of Raven motion is calculated as follows;

$V = \frac{Distance}{Time} \\\\V = Distance\ \times \ \frac{1}{Time} \\\\V = 2\frac{2}{5} \ miles \ \ \times \ \ \frac{1}{3/5 \ hr} \\\\V = \frac{12}{5} \ miles \ \ \times \ \ \frac{5}{3 hr} \\\\V = 4 \ mph$

The distance traveled by Raven in 1 hour at the given rate is calculated as follows;

$D = 4 \times 1\\\\D = 4 \ miles$
