Answer:
121 cm²
Step-by-step explanation:
The area (A) of a square is calculated as
A = s² ( s is the measure of the side )
Given perimeter = 44 cm , then
s = 44 ÷ 4 = 11cm , thus
A = 11² = 121 cm²
Answer:
Step-by-step explanation:
Let the initial price be x
<u>Then the reduced price is </u>
<u>If 5 mugs cost $28.20, we have equation:</u>
- (x - 1.75)*5 = 28.20
- x - 1.75 = 28.20/5
- x - 1.75 = 5.64
- x = 1.75 + 5.64
- x = 7.39
Initial price for 1 mug was $7.39
Angelica would have painted the bedroom in 20 hours if every hour she painted 1/20. But she doesn't paint 1/20 of a room per hour but rather 30 minutes. That means it will take her 10 hours to paint the whole room.
Hope this helps.
A^2-3a+14 is the answer :)
