5. Find the product of p(x) and q(x) if p(x) = 2x+7 and q(x) = 4x-9
stepan [7]

Answer:

p(x), q(x), and their product are all polynomials.

p(x) · q(x) = 6x² + 10x - 63

Step-by-step explanation:

First of all P(x) and q(x) are polynomials because polynomials refer to any sum, difference, or product of a collection of algebraic terms. The word polynomials is general. P(x) and q(x) are polynomials but more specifically they are binomials since they only have two terms. Their product is a polynomial as well, but more specifically its a trinomial because it has three terms.

<em>process of multiplying</em>

Using the distributive property (or foil method) when multiplying p(x) and q(x) you would first get the expression 6x² - 18x + 28x - 63. From here you would combine "like terms". This would give you your final answer of

6x² + 10x - 63. Sorry, I couldn't help you with the D question but I hope this helps ;)

An antique dealer usually charges 20 percent more than his purchase price any vase sold in his store.during a clearance sale,all
galina1969 [7]
The answer is c. 10%
We know that the antique dealer would normally charge 20% more than the price he purchased the item for. This also means that the antique dealer is making a profit of 20% on the items he sells. If the antique dealer hosts a 10% off sale, he is reducing the profit he is making from 20% to 10%.

The difference of 2.5 x 10^{4} - 1.5 x 10³ is 2.35 x 10^{4}.

<h3>What is the difference?</h3>

Difference is the result of the subtraction of two or more numbers. The numbers are written in scientific notation. Scientific notation is a method that is used to write large numbers.

The exponent of the numbers have different value. In order to evaluate them, they have to have the same values.

2.5 x 10^{4} - 1.5 x 10³

2.5 x 10^{4} - 0.15 x 10^{4}

2.35 x 10^{4}
