Answer:
Pual needs 3 gallons
Step-by-step explanation:
∵ The dimensions of the four walls are:
25 × 8 , 30 × 8 , 25 × 8 , 30 × 8
∴ The area of painting = 2(25 × 8) + 2(30 × 8)
= 400 + 480 = 880 square feet
∵ each gallon paint 400 square feet
∴ The number of gallons = 880/400 = 2.2, so he needs 3 gallons
Answer: B or the second choice
Step-by-step explanation:
well for triangle DEF since E is on the top left, it should be on the bottom right. While F was on the bottom right, it would be on the top left where E originally was. The angles inside has the same situation with E and F, however D stills stays at the top because when reflected like a mirror, D stays at the top. Sorry it’s long and hope this helps!
