How many times larger is 9 x 10000 to 5 x 1000
Whitepunk [10]
9 x 10,000 is B. 18 times larger than 5 x 1,000.

This can be found by simplying multiplying each pair of number (9 x 10,000 = 90,000) and ( 5 x 1,000 = 5,000) then dividing the smaller value (5,000) into the larger value (90,000). This will give you the answer of 18.

I hope this helps!

In the diagram, GB = 2x + 3..
zaharov [31]

<u>Answer-</u>

\boxed{\boxed{GB=15\ units}}

<u>Solution-</u>

From the attachment,

AD = AE, so FA is a median.

BD = BF, so BE is a median.

CF = CE, so DC is a median.

And G is the centroid.

From the properties of centroid, we know that

The centroid divides each median in a ratio of 2:1

So,

\Rightarrow FG:AG=2:1

\Rightarrow \dfrac{FG}{AG}=\dfrac{2}{1}

\Rightarrow FG=2\times AG

\Rightarrow 5x=2\times (x+9)

\Rightarrow 5x=2x+18

\Rightarrow 3x=18

\Rightarrow x=6

So, GB will be 2(6)+3=15 units

Help me simplify this problem please
Eva8 [605]
4x+2x^2+3x-2x+7
First, you would combine like terms. In this case, you would add 4x and 3x then subtract 2x. 
2x^2+5x+7

5x^2-2x+3+4x-2x^2
Once again, you must combine like terms. Subtract 2x^2 from 5x^2, then subtract 2x from 4x.
3x^2+2x+3

There you go! Hope it helps
