Answer:

x=9

Step-by-step explanation:

x + 3(2x - 5) = 4x – 12

distrubute left side

3 times 2x; 3 times -5

x+6x-15=4x-12

add like terms

x+6x

7x-15=4x-12

get all variables on the same side

7x-15=4x-12

-4x -4x

3x-15=12

add 15 to both sides

3x-15=12

+15 +15

3x=27

divide by 3 on both sides

3x/3=27/3

x=9

**A rock dropped from a 100 foot tower.

mars1129 [50]

Answer:

2.83 s

Step-by-step explanation:

We are given that

$h(t)=-16t^2+10t+100$

When a rock reached the ground then h(t)=0

$-16t^2+10t+100=0$

$16t^2-10t-100=0$

Using quadratic formula

$x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}$

$t=\frac{10\pm\sqrt{(-10)^2-4\times 16\times (-100)}}{2(16)}$

$t=\frac{10\pm\sqrt{100+6400}}{32}$

$t=\frac{10+\sqrt{6500}}{32}=2.83$

$t=\frac{10-\sqrt{6500}}{32}=-2.2$

Time cannot be negative .Therefore, negative value of t can not be possible.

Hence, the rock takes 2.83 sec to reach the ground.
