Which expressions show Sam's total profits from selling apples (a) and bananas (b)? Select two that apply. 1 0.40(a+b) 2 0.40a+0.40b 3 0.80(a+b) 4 0.40+a+0.40+b 5 0.40(ab) 6 0.80(ab)

0.40a + 0.40b

Step-by-step explanation:

Total Profit

= P(a,b) = ($0.40a) + ($0.40b),

where a = no. of apples sold and b = no. of bananas sold.

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11
