Rounding $32.14 to the nearest ten dollars results in $30, as $32.14 is below $35. Multiplying $30 by 0.15 (15%) gives us $4.50. The tip is approximately $4.50, and the total is approximately $36.64.

What is the product?<br> (6r-1)(- Br-3)

Andru [333]

Answer:

$-6Br^2-18r+Br+3$

Step-by-step explanation:

we have the expression:

$(6r-1)(- Br-3)$

We need to multiply the two terms in the first parenthesis by the two terms in the second parenthesis:

$(6r)(-Br)+(6r)(-3)+(-1)(-Br)+(-1)(-3)$

we solve each term taking into account the law of signs

(-)(-)=+

and

(+)(-)=-

also for the first term we use that $r*r=r^2$

thus we have:

$-6Br^2-18r+Br+3$

it can be simplified a little more if we factor an r of the second and third term:

$-6Br^2+r(-18+B)+3$
