Answer:

We get t= 7.22 and t=0.28

The correct options are Option A and Option G

Step-by-step explanation:

The height h of toy rocket at time t seconds after  launch is given by the equation

We need to find how many seconds  until the rocket is 40 feet?

We are given height of rocket h(t) = 40 feet

and we need to find time t

Using the equation we can find time t

We have h(t)=40

Now, we will solve the quadratic equation using quadratic formula:

We have a =16, b=-120 and c=32

Putting values and finding t

So, we get t= 7.22 and t=0.28

The correct options are Option A and Option G

Answer:

7x - 7

Step-by-step explanation:

In this equation you are going to add like terms.

The like terms you have are the terms with x and then the terms without the x.

So 4x + 3x = 7x

5 - 12 = -7

So your answer is 7x-7
