Answer:

7x^3 +11x^2 -5x -8

Step-by-step explanation:

Combine like terms.

(4x^3+6x^2+2x^2-3) + (3x^3+3x^2-5x-5)

= (4 +3)x^3 +(6 +2 +3)x^2 +(-5)x + (-3 -5)

= 7x^3 +11x^2 -5x -8

_____

Noting that the first expression contains two x^2 terms, we wonder if you actually want the sum ...

(4x^3+6x^2+2x-3) + (3x^3+3x^2-5x-5)

= (4 +3)x^3 +(6 +3)x^2 +(2 -5)x +(-3 -5)

= 7x^3 +9x^2 -3x -8

Answer:

The flour will last for about 11 days.

Step-by-step explanation:

Suppose, the flour will last for $x$ days.

She uses 15 pounds of flour each day. So, the total amount of flour used in $x$ days $= 15x$ pounds.

Given that, she has 157.86 pound of flour. So, the equation will be......

$15x= 157.86\\ \\ x= \frac{157.86}{15}=10.524 \approx 11$

Thus, the flour will last for about 11 days.
