What is the unit rate of 360 customers in 30 days

ad-work [718]

To find a unit rate, we need to divide the unit (days) by itself, and the x per y (customers) by the unit. In this case, we will be dividing 360 (number of customers) by 30 (days). When we do this, we can see that there are 12 customers per day.

nexus9112 [7]

Solution:

Given:

$(2x^2+2x+1)(4x-1)$

To get the product of the polynomial; we use the distributive property of multiplication.

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

$\begin{gathered} (4x-1)(2x^2+2x+1) \\ 4x(2x^2+2x+1)-1(2x^2+2x+1) \\ =8x^3+8x^2+4x-2x^2-2x-1 \\ \text{Collecting similar terms together and simplifying further;} \\ =8x^3+8x^2-2x^2+4x-2x-1 \\ =8x^3+6x^2+2x-1 \end{gathered}$

Therefore, the product of the polynomials is;
