Formula is 2(wl+hl+hw)
2[(7x20)+(15x20)+(15x7)]
=1090 cm^2
Answer:
Apply them sequentially.
Step-by-step explanation:
The store would apply the discounts sequentially because it gives less of a discount compared to if they did it all at once.

Answer:
(C) 2√15
Step-by-step explanation:
Recognize that all the triangles are right triangles, so are similar to each other. In these similar triangles, the ratio of the short side to the long side is the same for all.
... CB/CA = CT/CB
... CB² = CA·CT = 10·6 = 60 . . . . . . . . . . multiply by CA·CB; substitute values
... CB = √60 = 2√15 . . . . . . . take the square root; simplify

<em>Comment on this solution</em>
The altitude to the hypotenuse of a right triangle (CB in this case) divides the hypotenuse into lengths such that the altitude is their geometric mean. That is ...
... CB = √(AC·CT) . . . . as above
This is true for any right triangle — another fact of geometry to put in your list of geometry facts.
Answer:
The mean will increase, after the outlier is removed.
