Which expression is a sum of cubes?

SAT
1 answer:
svet-max [94.6K]3 years ago
6 0

Answer:

-27a³b⁶ + 8a⁹b¹²

Explanation:

Every term in the expression above every term is a perfect cube.

In the first term (-27a³b⁶), -27 is a perfect cube of -3 while the exponents of a and b are both divisible by three.

In the second term  (8a⁹b¹²),8 is a perfect cube of 2  while the exponents of a and b are divisible by three.

If the index of a number is divisible by three to give a whole number, the result of finding the cube root is a whole number hence a perfect cube root.

A food worker washes her hands before taking a torn package of dry pasta.
blsea [12.9K]

The hazard of the food worker that is most likely to make pasta unsafe to eat is;

A; Torn packaging fragments

Complete question is;

A food worker washes her hands before taking a torn package of dry pasta from the food storage area. She dumps the pasta In the stainless pot to cook.

What hazard is most likely to make pasta unsafe to eat?

A. Torn packaging fragments

B. Metal leaching from the pot

C. Pathogens from the worker’s hand

D. Soap residue from the worker’s hands

Food contamination can occur during packaging and storage of processed foods if the different quality standards that need to be followed are not observed.

Now, we are told that the package of dry pasta was torn before she put it into the stainless pot to cook. This means that ounce she washed her hands there is not likely to be any microbiological contamination but instead there will be chemical contamination that arises from fragments of the torn pasta package which could have entered inside it before putting into the cooking pot.

In conclusion, the hazard likely to have occurred to make the package unsafe to eat is called Torn packaging fragments.

In quadrilateral $ABCD$, we have $AB=3,$ $BC=6,$ $CD=4,$ and $DA=4$. If the length of diagonal $AC$ is an integer, what are all
Natalka [10]
<h3>Answer:</h3>

AC ∈ {4, 5, 6, 7}

<h3>Explanation:</h3>

When two sides of a triangle are specified, the allowable values for the length of the third side are between the sum and difference of the given sides.

In ∆ACD, sides DA and CD are both given as length 4. Thus the possible range of values for side AC is 0 – 8. The extremes of this range result in ∆ACD having zero area, so we assume they are not of interest.

In ∆ACB, sides AB and BC are given as having lengths 3 and 6. Thus the possible range of values for side AC is 3 – 9. The extremes of this range result in ∆ACB having zero area, so we assume they are not of interest.

The integers that are in both ranges and that give triangles with non-zero area are ...

... AC ∈ {4, 5, 6, 7}
