A prism has a surface area of 108 in². It is to be enlarged by a scale factor of 3.

Triangular prism with no labeled sides.

The surface area of a scaled figure equals the original surface area times the square of the scale factor.

What is the surface area of the enlarged prism?

36 in²
324 in²
972 in²
11,664 in²

Option A.

Step-by-step explanation:

Tina recorded the temperatures in one day.

Morning temperature : +5°F

Afternoon temperature : 0° F

Night temperature : (-1)°F

Now we will check each statement given.

A). The morning temperature was 5° above the afternoon.

Morning temperature - noon temperature = 5 - 0 = 5°F

Therefore, the given statement is true.

B). The morning temperature was 5° below the night temperature.

Morning temperature - night temperature = +5 - (-1)

                                                                     = 5 + 1 = 6° F

The given statement is false, because morning temperature is 6° higher than night.

C). The night temperature was 1 degree below the morning temperature.

Night temperature - morning temperature = (-1) - (+5) = (-6)°F

Since night temperature was 6 degree below the morning temperature.

Therefore, the given statement is False.

D). The night temperature was 1 degree above the afternoon temperature.

Night temperature - afternoon temperature = (-1) - 0 = -1° F

Therefore, night temperature was 1° below the afternoon temperature.

The given statement is False.

Option A. is the answer.
