Group like terms

-4g^4 - 3g^3 + g^2 + 3g^2 + 5g + 9 - 6

combining like terms:-

= -4g^4 - 3g^3 + 4g^2 + 5g + 3

<span>g^2 + (–4g^4) + 5g + 9 + (–3g^3) + 3g^2 + (–6)

</span><span>Group like terms.

This means that we need to group together terms with the same variable and exponent.

(-4g^4) this has no like terms so it will sit on its own
(-3g^3) same with this
(3g^2, g^2)
(5g)
(9, -6)

Now, we want to combine the like terms we just identified by adding them. When we add terms, we simply add the coefficients (The number before the variable). If a term does not show a coefficient (For example, g^2) then the coefficient is 1.

3g^2 + g^2 = 4g^2 (3 + 1 = 4)
9 + (-6) = 3

So, our final polynomial is </span><span>–4g^4 – 3g^3 + 4g^2 + 5g + 3. This is in standard form because the degrees of each term are in descending order.
The answer is B.

Hope this helps!!
Let me know if you need help understanding anything and I'll try to explain as best I can.

What is the answer to the Brain Teaser below
lawyer [7]

Answer:

19

Step-by-step explanation:

The boots are the value of 10, since 3 equal 30. The man is the value of 5 since there are two men (10) and one boot (also 10) which made 20. The ribbon is the value of 4 since there is one man (5) and 2 ribbons (8 ) which made 13. add 10, 5 and 4 and you get 19.

X/2 + 3/2 &lt; 5/2 give solution ​
Nataly [62]

Start with

\dfrac{x}{2}+\dfrac{3}{2}

Multiply the whole equation by 2. Since 2 is positive, we don't need to switch the inequality sign:

x+3

Subtract 3 from both sides:

x

A water tower casts a 100- foot shadow. At the same time, an 8- foot street sign casts a shadow of 6 feet. what is the height of
Elina [12.6K]
Set up and solve an equation of ratios.  Comparing shadow lengths, we get 100/6; comparing heights, we get x/8.  Set these two ratios equal to one another and solve the resulting equation for x:

100       x
----- = ------      Then 6x=800, and x = 800 feet^2 over 6 feet.  Your answer 
   6        8

must have the unit of measurement "ft."

If f(x) = x2 – 1 and g(x) = 2x – 3, what is the domain
Ainat [17]
Begin by finding the lowest point the quadratic equation can be, the vertex; 

x²-1= is just a translation down of the graph x²

vertex; (0, -1) and since the graph of x² would extend to infinity beyond that point, we can say {x| x≥0} for domain and {y| y≥-1}. 

For the linear equation, it is possible to have all x and y values, therefore range and domain belong to all real numbers. 

Hope I helped :)
