Answer:
$1346.40
Step-by-step explanation:
Find the volume of the pool first:
volume = cubiod + triangular prism
volume = (8*6*8) + (8*6*6)/2
volume = 528 cubic feet
price = price per cubic foot * cubic feet
price = $2.55 * 528 cubic feet
price = $1346.40
Answer:
B
Step-by-step explanation:
It's B because two negatives equal a positive.
C. The absolute value of -45 is 45, leaving the extra negative to hang on in there ---> -|-45|= 45= (bring the negative back over) -45
D. Self explanatory its -45 alone lol.
1 gallon is 16 cups, so that means that half a gallon is 8 cups. Therefore, from 1 and 1/2 gallons of soup you can get 24 1 cup servings.
Answer:
Step-by-step explanation:
The basic concept for both is the same, except with grouping you have more than 3 terms and after factoring out what is common in each group, you are left with identical terms in a set of parenthesis that can then also be factored out. For example, this would be factoring by grouping (then I will show you a factoring by GCF to better illustrate the idea):
If our polynomial is
we could group those terms into groups of 2 (without changing their order at all) to get:
and we factor out what's common in each group to get:
You can see that the (x - 1) is common now and can be factored out, leaving us with
(the secod term now can be factored if you need the complete linear factorization, but it will lead to imaginary numbers).
An example of factoring out the GCF is to factor out what's common in all the terms. It HAS TO BE COMMON IN ALL THE TERMS to do it this way. For example, in the polynomial
the GCF for all the terms is a 2, so that's all we can factor out. It has to factor out of every term every time, no exceptions:
The method of GCF factoring often just serves to simplify the polynomial down a bit, but sometimes will still require factoring.
Your answer is a Cross-sectional survey because it is in a large group.
