How do I multiply a polynomial by a binomial?

Vinvika [58]

Distributive property.

$a(b+c)=ab+ac$

$(a+b)(c+d)=a(c+d)+b(c+d)=ac+ad+bc+ad$

$(a+b+c)(d+e)=a(d+e)+b(d+e)+c(d+e)=ad+ae+bd+be+cd+ce$

and so on.

3. You sell storm windows and doors. You receive a straight

OLEGan [10]

Answer:

$\$3886.8$

Step-by-step explanation:

Commission received on selling each storm window $=8\%$ of the selling price of each storm window

Commission received on selling each door $=12\%$ of the selling price of each door

Amount earned on selling storm windows = $5,400

Amount earned on selling doors = $28,790

Commission received on selling storm windows $=\frac{8}{100}(5,400)=\$432$

Commission received on selling doors $=\frac{12}{100}(28,790)=\$3454.8$

Therefore,

Total commission received $=432+3454.8=\$3886.8$

Find the degree of the term -5x to the power of 4

marysya [2.9K]

Answer:

4 or -625x^4 (Just in case I misunderstood)

Step-by-step explanation:

The degree is always the power of something. Since -5x has a power of 4, its degree is 4.

Just in case I misunderstood the question, I will solve it another way that I think you meant. (-5x)^4 is -5^4 times x^4.

-625 times x^4 is -625x^4.
