Emily wants to buy a square tablecloth to cover a square card table. she knows the tabletop has an area of 9 square feet. what are the minimum dimensions of the tablecloth emily needs? [ ] feet by [ ] feet.

3 ft by 3 ft

Step-by-step explanation:

The minimum dimensions will be those of a square with an area of 9 ft².

The formula for the area of a square is

A = l²     Substitute the area

9 = l²     Take the square root of each side

l = 3

The minimum dimensions are 3 ft by 3 ft.

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3

ratio is 2 : 9

the answer is three

13.5 : 3
