Answer:
1920 square inches
Step-by-step explanation:
For a rectangular prism, the lateral area can be found by ...
LA = Pl
where P is the perimeter, and l is the length.
For a square pyramid, the lateral area can be found by ...
LA = (1/2)Ph
where P is the perimeter of the base, and h is the slant height of the triangular faces.
For a figure with a square cross section of perimeter P "capped" by square pyramids on either end, the total surface area is the sum of the lateral areas of the three components:
SA = (Pl) + (1/2)Ph + (1/2)Ph
SA = P(l+h) = (4×15 in)(14 +18 in) = (60)(32) in²
SA = 1920 in²
The surface area of the solid seems to be 1920 square inches.

<em>Caveat</em>
If the figure is something other than what we have tried to describe, your mileage may vary. A diagram would be helpful.
Answer:
<em><u>Incomplete question. However, additional information provided below</u></em>
<u>Step-by-step explanation</u>:
Here is a clearer rendering of the requirements of the question below:
"A supermarket delivers tickets to all its customers, for those who make purchases under $ 10 an orange ticket, purchases between $ 10 and $ 20 a yellow color, between $ 20 and $ 30 a blue color and for those who make larger purchases at $ 40 dollars a green ticket. To choose the winners, spin the roulette (as shown in the figure). Determine the probability that a person who spent $ 25 on purchases will win."
Thus, <u>you are required to focus your probability calculations on the $ 20 and $ 30 customers category who are given a blue color ticket, since a person who spends $25 is within this category.</u>
Answer:50
Step-by-step explanation:
Multiply both numbers to get answer
D.180+x=7x
x-7x=-180
-6x=-180
x=180/6
x=30 pounds
180+30=210
When you simplify the answer is -5m-33
