Answer:

$-7x^2+x$

Step-by-step explanation:

(4x2-x) from -3x2 is

Subtract $4x^2-x from -3x^2$

$-3x^2 - (4x^2-x)$

Remove the parenthesis by multiplying negative sign inside the parenthesis

$-3x^2 - 4x^2+x$

Now combine like terms, add -3 and -4 and it becomes -7

$-7x^2+x$

Find x 5[x^2]+5[x]-x^2-x=2004

a_sh-v [17]

The answer is either $x=\frac{-1}{2}+\frac{1}{2}\sqrt{2005}\\$ or $x=\frac{-1}{2}+\frac{-1}{2}\sqrt{2005}$

To solve: Let's solve your equation step-by-step.

5x2+5x−x2−x=2004

Step 1: Simplify both sides of the equation.

4x2+4x=2004

Step 2: Subtract 2004 from both sides.

4x2+4x−2004=2004−2004

4x2+4x−2004=0

Step 3: Use quadratic formula with a=4, b=4, c=-2004.

x= −b±√b2−4ac /2a

x= −4±√32080 /8

$x=\frac{-1}{2}+\frac{1}{2}\sqrt{2005}\\$ or $x=\frac{-1}{2}+\frac{-1}{2}\sqrt{2005}$

Answer:

1. A

2. G

Step-by-step explanation:

In 5 and 6, you see descriptions about leaves and their characteristics. Leaves are not the speaker, the person referenced in the poem is. Since leaves are being described and not the speaker, this means it's describing the setting.

The answer would be A.

You see the herons being described as 'blowing like smoke'. Smoke is swift and fast-moving, so it wouldn't be in the exact same place as before. This fits the description of G, which would be "swift and fleeting".

The answer would be G.

Answer:

4 blue marbles

Skills needed: Number Theory, Fractions

Step-by-step explanation:

1) The problem tells us that the jar contains marbles that are either red, green, or blue (No Other Color).

It also mentions that $\frac{2}{5} (\frac{4}{10})$ of the marbles are red

and that $\frac{1}{10}$ of the marbles are blue

- The given statement is that 20 marbles are green, and we need to find out the number of blue marbles.

2) We need to first find out the total number of marbles, and then multiply that by $\frac{1}{10}$ to get the # of blue marbles.

---> Given $\frac{4}{10}$ are red and $\frac{1}{10}$ are blue, $1-\frac{1}{10}-\frac{4}{10}$ of the marbles are green (since fractions add up to 1 whole)
