Answer: hope this helps

Step-by-step explanation:

Write down the numbers, one under the other, with the decimal points lined up.

Put in zeros so the numbers have the same length (see below for why that is OK)

Then add, using column addition, remembering to put the decimal point in the answer.

Find the GCF of <img src="https://tex.z-dn.net/?f=18x%5E%7B3%7D" id="TexFormula1" title="18x^{3}" alt="18x^{3}" align="absmiddle

melamori03 [73]

18x^3 = 6x^3 * 1

30x^5 = 6x^3 * 5x^2

So GCF = 6x^3

Answer

6x^3

What factors multiply to -80 and add to 6

forsale [732]

80 = -1(80), -2(40), -4(20), -5(4),

Total answers include: -81, 79, -42, 16, -9, and 1.

None of them add up to 6!

Are you doing polynomial equations?

If so, you can solve it the hard way.

x^2 + 6x -80 = 0

(x^2 + 6x + 9) - 80 = 9

(x+3)^2 = 89

(x+3) = 9.43

x = 6.43

If you're not doing those then I'm afraid your question has no answer.

Hope that helps!

The lowest elevation in Lammefjord, Denmark, is 23 feet below sea level. The elevation of the Sea of Galilee in Israel is about

tatyana61 [14]

Answer:

$Sea\ of\ Galilee = -690ft$

Step-by-step explanation:

Given

$Lowest\ Elevation = 23ft$ below sea level

Sea of Galilee = 30 times Lowest in Lammefjord, Denmark

Required

Determine the elevation of the Sea of Galilee

We have that the lowest elevation in Lammefjord is:

$Lowest\ Elevation = -23ft$

It is negative because, the elevation is below sea level.

Calculating the elevation of Sea of Galilee, we have:

Sea of Galilee = 30 times Lowest in Lammefjord, Denmark

$Sea\ of\ Galilee = 30 * -23ft$

$Sea\ of\ Galilee = -690ft$

<em>Hence, the elevation of Sea of Galilee is -690ft or 690ft below sea level</em>
