Add: 2x² - 8x -9 and 3 x² + 8x-2​
Delvig [45]

Answer:

<h2>5x^2 - 11</h2>

Step-by-step explanation:

We got to add these together so

2x^2-8x-9+3x^2+8x-2

the 2x^2 and 3x^2 add to 5x^2

the 8x and -8x cancel each other out

the -9 and -2 add to -11

so..

5x^2 - 11

I hope this helped :)

Jake eats 1/4 of a. box of cereal in 1/8 of a month. How many boxes will Jake eat in a month?
Sergeeva-Olga [200]
~2 boxes

If a month is about 31 days 1/8 of that would be ~31/8

That number can be rounded to 4

If 1/4 of a box is eaten even 4 days, one box will be eaten after 16 days

1 box in 16 days = 2 boxes is ~31 days

~ = about
