See attached for my work. <em>If you are color blind let me know, I color-coded where I "pulled" numbers from.</em>
To answer this problem, we can look at the graph. We need to see for how long the black line is above the blue.
Answer:
x = 3 ± sqrt(11)
Step-by-step explanation:
x^2 - 6x + 9 = 11
Recognizing that this is a perfect square trinomial
(x-3) ^2 =11
Taking the square root of each side
sqrt((x-3) ^2) = ± sqrt(11)
x-3 =± sqrt(11)
Add 3 to each side
x = 3 ± sqrt(11)
Part A number of combinations of 8 from 10 = 10C8 = 10C2
= 10*9 / 2 = 45
Part B Number combinations = 10C4 = (10*9*8*7)/ (4*3*2) = 210
Total number of ways = 45 * 210 = 9450 (answer)

Ex: A square pyramid has 5 faces, the base of the square pyramid has 4 sides.
4+1=5
Answer:
<em>12 cans and 14 boxes.</em>
Step-by-step explanation:
A/Q
6 cans are sold with 7 boxes, i.e; total of 6+7 = 13
as the market sold 26 cans and boxes, we can calculate each by dividing from the usual total.
26/13 = 2
they sold double their usual total.
so, if they normally sold 6 cans they sold its double, 6×2 = 12
the double of normal boxes would be 7×2 = 14
