Solve the equation (x-4)(2x+3) = 4

Marina CMI [18]

Answer:

(x-4.34)(x+1.84)=0

Step-by-step explanation:

2x^2 -5x-16=0

delta=

$25 + 4 \times 2 \times 16 = 153$

x1,2=

$(5 + \sqrt{153} ) \div 4 = 4.34 \\ (5 - \sqrt{153} ) \div 4 = - 1 .84$

Two trains leave stations 546 miles apart at the same time and travel toward each other. One train travels at 95 miles per hour

Ira Lisetskai [31]

Answer:

It will take 2 hours 36 minutes for the two trains to meet.

Step-by-step explanation:

The distance between the two trains is decreasing by $95+115= 210$ miles per hour, which can be written as $\frac{210 miles}{1 hour}$ .

So at this rate, the distance between the trains will be reduced to zero in:

$\frac{546 miles}{\frac{210 miles}{1 hour} } = 476 miles * \frac{1 hour}{210 miles}$

$= \frac{546}{210} = 2.6 hours$

Changing 2.6 hours to hours and minutes:

$2 hours + 0.6 hours = 2 hours + (0.6 * 60) = 2 hours + 36 minutes$

Therefore, it will take 2 hours 36 minutes for the two trains to meet.
