Answer:

At 3.44 seconds, the penny is at a height of 300 meters above the ground.

Step-by-step explanation:

Basically, we have to solve an equation here:

-4.9t^{2} + 358 = 300

Hence,

-4.9t^{2} = 300 - 358

t^{2} = \frac{-58}{-4.9}

t = 3.44

Hence, at 3.44 seconds, the penny is at a height of 300 meters above the ground.

Hope this helped!

Answer:

<h2><em><u>ᎪꪀsωꫀᏒ</u></em></h2>

➪x= 3

Step-by-step explanation:

4x-(8-x)-2=9x-20+x-5

=> 5x-10 = 9x-20+x-5

=> -10+5 = 10x-20-5x

=> -5+20 = 5x

=> 15 =5 x

=> 15/5 = x
