Step-by-step explanation:

t in 1200m:

t =  \frac{4500}{x}  \\ x = 1200 \\ t = 4500 \div 1200 = 3.75

t in 3750:

t =  \frac{4500}{x}  \\ x = 3750 \\ t = 4000  \div 3750 = 0.12

difference is:

3.75-0.12 = 3.63

Answer:

15\sqrt{x}

Step-by-step explanation:

\sqrt{(25*9)x}

Start by "taking out" the perfect squares. 25 and 9 are perfect squares (and pretty common ones).

The square root of 25 is 5 and the square root of 9 is 3. Therefore you can take out a 5 and 3 from the radical. Multiply the numbers you take out together.

5 * 3 = 15

The number outside of the radical sign will be a 15, and x is left over inside the radical. The final answer is 15\sqrt{x}.

Helppp meeeeeeeeeeeeeee
Leni [432]

Measuring the figure with a ruler, length = 2 inch and width = 1.5 inch

It is given that 1/2 inch = 4 feet

1 inch = 4*2 = 8 feet

Area of rectangle = length * width

Length = 2*8 =  16 feet

Width = 1.5*8 =  12 feet

Area of Quintoe's bedroom = 16 feet * 12 feet = 192 feet^2

Hence option C is correct.
