The scale given (1 in : 1/2 ft) implies that 1 inch on the model is equal to 1/2 foot on the actual ship. Therefore, we can multiply the two inch values by 1/2 foot to find the true dimensions of the ship in feet. Starting with 28 inches:
28 × (1/2 ft) = 14 ft
28 inches is proportional to 14 feet. Now calculate 65 inches:
65 × (1/2 ft) = 32.5 ft
65 inches is proportional to 32.5 feet. Therefore, the answer to this problem is:
D) 14 ft. by 32 1/2 ft.
I hope this helps!

Answer:
6
Step-by-step explanation:
We want to expand this; (x + y)⁴
This can be written as;
(x + y)² × (x + y)²
This gives;
(x² + 2xy + y²) × (x² + 2xy + y²)
This gives;
x²(x² + 2xy + y²) + 2xy(x² + 2xy + y²) + y²(x² + 2xy + y²) = x⁴ + 2x³y + x²y² + 2x³y + 4x²y² + 2xy³ + x²y² + 2xy³ + y⁴
Simplifying gives;
x⁴ + 4x³y + 4xy³ + 6x²y² + y⁴
Thus, the coefficient of x²y² is 6
5.38 in expanded form is 5 + 0.3 + 0.08
Expanded form means you have to break it apart into addition.
