Answer:
the total surface area is 40 + 12 + 15 = 67 square units
Step-by-step explanation:
Refer to the diagram:
the combined area of the top and bottom is 2(5·4) = 40:
the combined area of the ends is 2(1.5·4) = 12; and
the combined area of the front and back is 2( 5 · 1.5) = 15
and so the total surface area is 40 + 12 + 15 = 67 square units
Answer:
The number of different platters Selena can create by selecting two different vegetables is 60 different platters
Step-by-step explanation:
The information given are;
The number of different sizes of salad available = 4
The number of different vegetable to choose from = 6
The number of vegetables Selena ordered = 2
The number of ways Selena can choose 2 vegetables out of 6 = ₆C₂ = 15 ways
The number of different platters (choice of vegetable and size of platter) Selena can create = The number of different sizes of salad available × The number of ways Selena can choose the vegetables
The number of different platters (choice of vegetable and size of platter) Selena can create = 4 × 15 = 60 different platters.

Answer:
Step-by-step explanation:
Lots of factoring here. Let's rewrite everything in its simplest, factored form:

The term (x - 4) cancels out completely, leaving us with

Let's get rid of that (x + 4) by multiplying both top and bottom by (x + 4) to get

It's obvious now that the (x + 3) term cancels out, leaving us with

Now all that's left to do is to FOIL out the numerator:

The first choice is the one you want
