What i don't understand sorry I couldn't help because im only in 5th grade im sorry
Answer:
The surface area is A≈96ft²
About 7
because 5^2+5^2 is 50 and then you take the sq root of 50 which is about 7
Amount after 9 years = 3600( 1 + 0.024)^9 = $4456.58
A = lw
A = (x + 6)4x
A = (x)4x + (6)4x
A = 4x² + 24x
