Answer:
The length of a rectangle is (2x + 4) and the width is (3x - 2) with a perimeter of 104cm.
Write and solve an equation to determine the length and width of the rectangle. Explain how you
determine your answer.
Answer:
972
Step-by-step explanation:
The first term is (9x)^3, so the coefficient of x is 9. Since the degree is 3, the second term must have a multiplier of (3 choose 1). 1458 / (3 choose 1) = 486.
486 / (9^2) = 6. Therefore, the coefficient of y must be 6. Since the second term is negative, the coefficient of y is also negative. Thus, this can be written as (9x-6y)^3. Solving for the xy^2 term gives us (3 choose 2) * 9 * 6^2 = or the third option.

Answer:
9
Step-by-step explanation:
Given that:
Dimension of Original photo = 4 inches by 6 inches
Intended dimension of model = 3 feet by 4 1/2 feets
Converting from feets to inches :
1 foot = 12 inches
Therefore,
Intended dimension of model :
3 feets = (3 * 12) = 36 inches
by 4 1/2 feets = (4 1/2 * 12) = 54 inches
Hence, scale factor required :
36 /4 = 9
54 / 6 = 9
Scake factor = 9
