The perimeter of a rectangle can be written out as follows;

\begin{gathered} P=(4x-5)+(2x-1)+(4x-5)+(2x-1) \\ P=2(4x-5)+2(2x-1) \\ P=2(\lbrack4x-5\rbrack+\lbrack2x-1\rbrack) \\ (b)The\text{ perimeter therefore is} \\ \text{Perimeter}=2(4x-5+2x-1) \\ \text{Perimeter}=2(6x-6) \\ \text{Perimeter}=12x-12 \end{gathered}

Alexandra has $15 to buy drinks for her friends at the baseball game. Soda
EleoNora [17]

Answer:

C

Step-by-step explanation:

write an equation for the costs:

if x is the number of sodas

and y is the number of waters

2.75x + 2y <= 15

(<= is less than or equal to)

if we substitute 3 for y

we get 2.75x + 2(3) <= 15

2.75x + 6 <= 15

2.75x <= 9

9 / 2.75 = 3.2727

however, you cannot buy part of a soda

so, round to 3

you also cannot buy negative sodas

so, the answer is C
