Answer:

r^2 + 14r + 33

Step-by-step explanation:

Apply the "FOIL" method for multiplying two binomials:

(r+3) (r+11) = r^2 (first terms) +

                    + 33 (last terms) +

                     + 11r (outer terms) +

                      + 3r (inner terms)

Combining ilke terms, we get:

r^2 + 14r + 33

Sylvia bought 1.5 pounds of dried apricots. She spent a total of 9.75. How much would 1 pound cost?
solong [7]

Set up a proportion:


\frac{1.5}{9.75} = \frac{1}{x}


The numerators represent the amount of pounds of apricots, and the denominators represent the cost of the apricots.


Cross multiply:


1.5x = 9.75


Divide both sides by 1.5 to get x by itself:


\boxed{x = 6.5}


A pound of dried apricots would cost $6.50.
