<h2>Answer:</h2>

The value of a is: 0

<h2>Step-by-step explanation:</h2>

We are given a expression by:

Quantity 4 times x times y cubed plus 8 times x squared times y to the fifth power all over 2 times x times y squared.

which is mathematically written as:

=\dfrac{4xy^3+8x^2y^5}{2xy^2}

Now, this expression could also be written as:

=\dfrac{4xy^3}{2xy^2}+\dfrac{8x^2y^5}{2xy^2}

Since,

\dfrac{a+b}{c}=\dfrac{a}{c}+\dfrac{b}{c} )

Now, on further simplifying we have:

=2x^{1-1}y^{3-2}+4x^{2-1}y^{5-2}

since,

\dfrac{x^m}{x^n}=x^{m-n}

Hence, we have :

=2x^0y^1+4x^1y^3

Hence, on comparing it with:

2x^ay^b+4x^cy^d

we have:

a=0,\ b=1\ ,\ c=1\ and\ d=3

You want the exponent of x in the first term of ...

\dfrac{4xy^3+8x^2y^2}{2xy^2}=\frac{4}{2}x^{(1-1)}y^{(3-2)}+\frac{8}{2}x^{(2-1)}y^{(2-2)}\\\\=2x^0y^1+4x^1y^0


The exponent a is 0.

1 tank of propane holds 5 gallons and will last 12 hours. how many gallons of propane is needed for 240 hours.
MAVERICK [17]

5 gallons        x gallons

------------- = ----------------

12 hours       240 hours


using cross products

5 * 240 = 12 * x

1200 = 12 x

divide each side by 12

1200/12 = 12x/12

100 =x

You will need 100 gallons

F(x) = -2x + 5<br> f ( ) = 13
scZoUnD [109]

Answer:

Okay, I haven't done this a long time however I believe with this you have to solve the equation by doing substitution.

Step-by-step explanation:

so, if f (x) equals 13, you replace the x in the equation to 13.

f(x)=-2x+5

f(x)=-2(13)+5

f(x)=26+5

f(x)=31

I believe 41 would be your answer. Hope this is right and it helped!

Are 3(h+4) and 3h + 12 equivalent? Explain using the table from Question 4.
Kruka [31]
Yes because once you distribute the 3 in the first equation it turns it into 3h+12
