m^2 -11m -60 = 0
m^2 -11m =60
(m^2 -11m + 121/4) = 361/4
(m - 11/2)^2 = 361/4
m - 11/2 = + or - 19/2
m = 11/2 + 19/2, 11/2 - 19/2
m = 15, -4
---------------------------------------------------
m^2 -11m -60
(11 +- Square root (121 +240))/2
11/2 +- 19/2
m= 15, -4
----------------------------------------------------
m^2 -11m -60
(m - 15) (m + 4)
m = 15, -4

Answer:
30 boxes of tea
Step-by-step explanation:
27 (overall tea boxes) - 12 (boxes sold) = 15
15 (leftover boxes) x 18 (kg of each box) = 270
270 (overall kg of the boxes) divided by 9 (kg of the bags) = 30, so all the tea boxes can be placed into the bags

Answer:
88 cm²
Step-by-step explanation:
Top small rectangular prism: (1 x 2 x 2) + (3 x 2 x 2) + (1 x 3) = 19
Bottom: (6 x 2 x 2) + (2 x 3 x 2) + (5 x 3) + (6 x 3) = 69
SA = 19 + 69 = 88
