Distributive property of division over subtraction

Mathematics

<u>Distributive property of division over subtraction:</u>

We know distribution means dividing one element to multiple element. Hence distributing property means if we multiply two set of number, like two elements in bracket and one outside the bracket, then the result will  be same as the multiplication of individual elements. As example, x\times(y+z) = x\timesy + x\times z

So generally it works on multiplication over addition, and directly do not work on division over subtraction.

But division over subtraction can work only in case of reciprocals as division is opposite of multiplication and subtraction can be done by adding one positive and one negative numbers.

Example,

\frac{(x-y)}{z} = \frac{(x+(-y))}{y} = \frac{x}{z} =\frac{x}{z}-\frac{y}{z}

But \frac{z}{(x-y)} case will not work.

Harriet earns the same amount of money each day. Her gross pay at the end of 7 work days is 35h + 56 dollars. Which expression r
Aleks [24]

Answer:

<em>The expression that represents her gross pay each day will be:  (5h+8) dollars.</em>

Step-by-step explanation:

Suppose, Harriet's gross pay each day = x

So, her total gross pay for 7 work days =7*x= 7x

Given that, her gross pay at the end of 7 work days is (35h + 56) dollars.

So, the equation will be.......

7x= 35h+56 \\ \\ x=\frac{35h+56}{7}\\ \\ x=\frac{35h}{7}+\frac{56}{7}\\ \\ x=5h+8

Thus, the expression that represents her gross pay each day will be:  (5h+8) dollars.

Multiply............
ZanzabumX [31]
Hey there!

In order to multiply these polynomials together, you will take both terms of the first polynomial and multiply them by each term in the second polynomial. You can then combine any like terms to get your final answer. 

(2x² – 5x)(4x² – 12x + 10)

2x² × 4x² = 8x⁴
2x² × –12x = –24x³
2x² × 10 = 20x²

–5x × 4x² = –20x³
–5x × –12x = 60x²
–5x × 10 = –50x

Write all of these terms together. You can rearrange the similar ones to be next to each other. 

8x⁴ – 24x³ – 20x³ + 20x² + 60x² – 50x

Just add or subtract the terms to simplify, if they can be.

8x⁴ – 44x³ + 80x² – 50x

(8x⁴ – 44x³ + 80x² – 50x) will be your final answer. 

Hope this helped you out! :-)
