**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**

I don’t know but you should give me brainlist because it sounds cool

**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
