Answer:

SA= 222cm ^2

Step-by-step explanation:

Surface area of the prism = (Perimeter of the base of the prism) × height + 2(area of the base)

Perimeter of the base = 5 + 3 + 2 + 2 + 2 + 3 + 5 + 8

= 30

Area of the base = 8×5 - 2×2 = 36 cm²

Surface area of the prism = 30×5 + 2×(36)= 222 cm²

Anna and Maya are competing in a dance tournament where dance moves are worth a certain number of points if a dance move it's do

Gre4nikov [31]

Anna's current number of points = 225 points.

She danced correctly and earned = 75 points.

And when she danced incorrectly she loses = 30 points.

Note: For dancing correctly earned points will be added and for dancing incorrectly loses points will be subtracted from the total points has in starting.

So, we can setup an expression as

Current points + earned points - loses points

Plugging values, we get

225 +75 -30 Required expression.

Adding 225 and 75, we get 300.

Therefore, 225 +75 -30 = 300-30.

Subtracting 30 from 300, we get

300-30=270.

Therefore, Anna's final score is 270 points.
