The question is asking us to find the sum. To do this, let's first write the original equation and then take it from there.
(3 x^{2}  + 3x - 5) + (-7 x^{2}  + 9)<span>
Use distributive property:
</span>3 x^{2}  + 3x - 5 - 7 x^{2}  + 9
Combine Like Terms:
&#10;-4 x^{2} +3x+4
Therefore, the answer to your question is -4x² + 3x + 4. Hope this helps and have a fantastic day!

Anon25 [30]

Answer:

Samuel slept for 1/4 of the distance.

Step-by-step explanation:

The information provided are:

  • Samuel fell asleep halfway home.
  • He didn't wake up until he still had half as far to go as he had already
  • gone while asleep.

Consider that the total distance covered was 1.

Then from the first point we know that Samuel fell asleep after covering a distance of 1/2.

It is provided that he woke up only after covering half of the remaining distance.

That is, he slept for 1/4 of the remaining distance.

Thus, Samuel was asleep for 1/4th of the entire trip home.

What is the distance between (-6, 2) and (8, 10) on a coordinate grid?
lawyer [7]

Answer:

The answer is 2(the square root of 65 )

Step-by-step explanation:

Plug ( -6, 2) and (8, 10) into the distance formula and solve.

Distance = the square root of ((x2 - x1)^2 + (y2 - y1)^2))

Distance = the square root of ((8 - -6)^2 + (10 - 2)^2))

Distance = the square root of (14^2 + 8^2)

Distance = the square root of (196 + 64)

Distance = the square root of 260 which can be simplified to 2(the square root of 64)
