Anyone who actually knows the real answer will get brainliest.

The answer would be 126 square inches because you have to break up the figures and figure out the area for each one so for the rectangle the area would be 75 because of the formula length times width then for the square it would be 16 because the formula is the side (squared) then for the last one the parallelogram it would be 35 because of the formula base times height. Hope this helped :)

Which of the following represents a geometric series <br> 2+6+18<br> 2,6,10<br> 2+6+10+<br> 2,6,18
quester [9]

good morning,

Answer:

2,6,18

Step-by-step explanation:

6/2=3 and 18/6=3 then 2,6,18 represent a geometric series.

6/2=3 and 10/6≠3 then 2,6,10 doesn’t represent a Géométric series.

A sandwich costs $0.75 more than a container of milk. A customer buys 4 sandwiches and 4 containers of milk. The customer pays $
Step2247 [10]
Assume that the cost of the milk is x.
We are given that a sandwich costs 0.75$ more than the cost of milk. This means that:
cost of sandwich = cost of milk + 0.75
cost of sandwich = x + 0.75

Now, the customer bought 4 sandwiches and 4 containers of milk at the cost of 7$.
We will transform this into an equation as follows:
total cost = cost of 4 sandwiches + cost of 4 containers of milk
7 = 4(x+0.75) + 4(x)

Solve the above equation to get x as follows:
7 = 4x + 3 + 4x
7-3 = 8x
8x = 4
x = 0.5

Therefore:
cost of milk = x = $0.5
cost of sandwich = x+0.75 = 0.5+0.75 = $1.25
