1. 538 - 247 = ?

2. 8 - 7 = 1

3. You can't subtract 3 and 4, so you have to take number from 5 (turning it into a 4) and then you add a 1 right next to 3 (which makes it 13;13 - 4 = 9

4. 4 - 2 = 2

538 - 247 = 291

So the answer is 291.

Subtract 8 y^2 − 5 y + 7 from 2 y^2 + 7 y + 1 1 <br><br> The answer is: −6y ^2 +12y+4

lys-0071 [83]

Answer:

$\large\boxed{-6y^2+12y+4}$

Step-by-step explanation:

$(2y^2+7y+11)-(8y^2-5y+7)\\\\=2y^2+7y+11-8y^2-(-5y)-7\\\\=2y^2+7y+11-8y^2+5y-7\qquad\text{combine like terms}\\\\=(2y^2-8y^2)+(7y+5y)+(11-7)\\\\=-6y^2+12y+4$
