Answer:

b

Step-by-step explanation:

one trip = 2724 miles

one round trip = 2 trips = 2724 * 2 = 5448 miles

We want to see how many round trips go into the miles needed for a free flight. We want to see how many times 5448 goes into 25000. To do this, we can use division.

25000/5448 ≈ 4.6

If we only have 4 round trips, it will not be enough for 4.6, so we will not be able to obtain a free flight. If we have 5, we will be able to, as 5 > 4.6

Answer:

We will choose option D.

Step-by-step explanation:

In the given diagram the shown right triangle has Base = 3 units, Perpendicular = 4 and the Hypotenuse = 5 units,

Now, in option A.

The vertices of the triangle are (-3,-3), (-3,4) and (4,-3).

Hence, the side lengths of the triangle are 7 units, 7 units, and 7√2 units.

So, it is not similar to the graphed triangle.

{Since, the ratio of corresponding sides of the similar triangles are the same}

Now, in option B.

The vertices of the triangle are (-3,-3), (-3,5) and (4,-3).

Hence, the side lengths of the triangle are 7 units, 8 units, and 10.63 units.

So, it is not similar to the graphed triangle.

Now, in option C.

The vertices of the triangle are (-3,-3), (-3,4) and (3,-3).

Hence, the side lengths of the triangle are 6 units, 7 units, and 9.21 units.

So, it is not similar to the graphed triangle.

Now, in option D.

The vertices of the triangle are (-3,-3), (-3,5) and (3,-3).

Hence, the side lengths of the triangle are 6 units, 8 units, and 10 units.

So, it is similar to the graphed triangle.  

This is because the ratio of the corresponding sides of the given triangle and the graphed triangle are same and it is 2.(Answer)

WILL GIVE BRAINLIEST... Find a polynomial, of degree 3, with integer coefficients that has zeros of x=2, x=-1 and Show all work
IrinaK [193]

Answer:

( x - 3i ) ( x + 3i )

 

= x^2 + 3xi - 3xi - 9i^2

 

= x^2 - 9 (-1)

 

= x^2 + 9

 

(x^2 + 9 ) ( x + 5 )

 

Now the left hand side is equal to the right hand side.

 

Good luck!
