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.

Answer:

The answer to your question is: midsegment = 35 units

Step-by-step explanation:

Use the Thales' theorem

                          \frac{3x + 55}{6x + 5} = \frac{86}{43} \\

                          43( 3x + 55) = 86( 6x + 5)

                          129x + 2365 = 516x + 430

                          129x - 516x = 430 - 2365

                          -387x = -1935

                           x = -1935 / -387

                           x = 5

Midpoint length = 6(5) + 5

                           = 30 + 5

                          = 35 units

Maria practiced for her piano recital each day for three days. the first day she practiced for 3/4 hour, the second day she prac
ZanzabumX [31]
To make this easier, we can convert the fractions into decimals. 3/4 is 0.75. 1 and 1/2 would be 1.50 and 2 and 1/4 would be 2.25. Now, let us to the subtraction in order for us to know the difference of each. So 1.50 minus 0.75 would be 0.75. And 2.25 minus 1.50 is also 0.75. 0.75 is 3/4 and this means that she increased 3/4 hour each day.
