Find the sum(x2 + 2x + 3) + (3x2 + x + 1)

Sum of (x²+ 2x + 3)  and (3x² + x + 1) is:

4x²+3x+4

Step-by-step explanation:

Find the sum of:

(x²+ 2x + 3)  and (3x² + x + 1)

(x²+ 2x + 3) + (3x² + x + 1)

Combining the like terms, we get

= x²(1+3)+x(2+1)+(3+1)

=4x²+3x+4

Hence, sum of (x²+ 2x + 3)  and (3x² + x + 1) is:

4x²+3x+4

p ≥ 13

13 pizzas at least

Step-by-step explanation:

$107 + $4 = $111

$111/$9 = 12.3333 round it to 13

now we know he needs to sell at least 13 pizzas so the inequality p= 13 or p > 13.

This is my go at it, I am not sure though.
