A is the correct answer.

The first term is, <span> <span>z2</span> </span> its coefficient is <span> 1 </span>.
The middle term is, <span> +z </span> its coefficient is <span> 1 </span>.
The last term, "the constant", is <span> -2 </span>

Step-1 : Multiply the coefficient of the first term by the constant <span> <span> 1</span> • -2 = -2</span> 

Step-2 : Find two factors of  -2  whose sum equals the coefficient of the middle term, which is  <span> 1 </span>.

<span><span>     -2   +   1   =   -1</span><span>     -1   +   2   =   1   That's it</span></span>


Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above,  -1  and  2 
                     <span>z2 - 1z</span> + 2z - 2

Step-4 : Add up the first 2 terms, pulling out like factors :
                    z • (z-1)
              Add up the last 2 terms, pulling out common factors :
                    2 • (z-1)
Step-5 : Add up the four terms of step 4 :
                    (z+2)  •  (z-1)
             Which is the desired factorization

<span>Equation at the end of step  3  :</span><span> 3 • (z + 2) • (z - 1) = 0 </span>

If it took Carlos 30 minutes to cycle from his house to the library yesterday, was the distance that he cycled greater than 6 mi
Ivanshal [37]

Answer:

1) No

2) Yes

Step-by-step explanation:

Given : If it took Carlos 30 minutes to cycle from his house to the library yesterday.

To find : Was the distance that he cycled greater than 6 miles?

Solution :

The relation between speed , distance and time is

\text{Distance}=\text{Speed}\times \text{Time}

1) The average speed at which Carlos cycled from his house to the library yesterday was greater than 16 feet per second.

Speed = 16 feet per second

Converting into miles, s=\frac{16}{5280}

Time = 30 minute

Converting into seconds, t=30\times 60

The distance he covered is

\text{Distance}=\frac{16}{5280}\times30\times 60

\text{Distance}=5.45\text{ miles}

No, the distance that he cycled is not greater than 6 miles.

2) The average speed at which Carlos cycled from his house to the library yesterday was less than 18 feet per second.

Speed = 18 feet per second

Converting into miles, s=\frac{18}{5280}

Time = 30 minute

Converting into seconds, t=30\times 60

The distance he covered is

\text{Distance}=\frac{18}{5280}\times30\times 60

\text{Distance}=6.13\text{ miles}

Yes, the distance that he cycled is greater than 6 miles.
