78. How can the polynomial, 18x^2 + 30x^6 be factored using the GCF?
dexar [7]

Answer:

6x^2(5x^4 +3)

Step-by-step explanation:

The greatest common factor of 18 = 3·6 and 30 = 5·6 is 6.

The greatest common factor of x^2 and x^6 is x^2.

Factoring 6x^2 from both terms, we get ...

... 18x^2 +30x^6 = 6x^2(3 +5x^4)

_____

<em>Comment on the question</em>

Since this answer is not among the answer choices, I suggest you ask your teacher to demonstrate how this problem is worked.

It appears as though the answers go with the problem 18x^9 +30x^6. Maybe there's a typo somewhere. For that problem, the best choice is the 2nd answer.

Megan cut a string into 4 equal pieces. Each piece is 4 fifths of a foot long. How many feet long was the string before Megan cu
worty [1.4K]

Answer:

Total = 3\frac{1}{5}ft

Step-by-step explanation:

Given

Pieces = 4

Size = \frac{4}{5}ft

Required

Determine the total size of the string

To do this, we multiply the number of pieces by the length of each piece.

Total = Pieces * Size

Total = 4 * \frac{4}{5}ft

Total = \frac{4 * 4}{5}ft

Total = \frac{16}{5}ft

Convert to mixed number

Total = 3\frac{1}{5}ft
