The area of the room = (40 x 24) - (20 x 12)

Area = 960 - 240 = 720 square feet

Divide square feet by width of a strip:

720 / 12 = 60 linear feet.

The answer is D.

Answer : The correct option is, (D) 60

Step-by-step explanation :

First we have to calculate the area of room.

Area of room = Area of big rectangle + Area of small rectangle

Area of rectangle = Length × Width

Area of room = (40 × 12) + (20 × 12)

Area of room = 720 square feet

Now we have to calculate the number of linear feet will he need to buy.

Number of linear feet = \frac{\text{Area of room}}{\text{Width of carpet strips}}

Number of linear feet = \frac{720}{12}=60

Thus, the number of linear feet will he need to buy is, 60

In order to find this, we need to count exactly how many times each of them blinks within 60 seconds. Then, we find which numbers are the same.

4, 8, 12, 16, 20, 24, 28, 32, 36, 40, 44, 48, 52, 56, 60

6, 12, 18, 24, 30, 36, 42, 48, 54, 60

Now, I will bold the numbers that are the same.

4, 8, 12, 16, 20, 24, 28, 32, 36, 40, 44, 48, 52, 56, 60

6, 12, 18, 24, 30, 36, 42, 48, 54, 60

Now, we have our answer.

Answer: The two neon lights will blink on the 12, 24, 36, 48, and 60 second marks.

Hope I helped!

Find all complex solutions of X^2-5X -5= 0
denis-greek [22]

ANSWER

x  =  \frac{ 5  -  3\sqrt{ 5} }{2}  \: or \: x  =  \frac{ 5 +3 \sqrt{ 5} }{2}

EXPLANATION

The given equation is

{x}^{2}  - 5x - 5 = 0

The solution is given by the formula

x  =  \frac{ - b \pm \sqrt{ {b}^{2}  - 4ac} }{2a}

where a=1, b=-5, c=-5

We substitute into the formula to get;

x  =  \frac{ -  - 5 \pm \sqrt{ {( - 5)}^{2}  - 4(1)( - 5)} }{2(1)}

We simplify to get,

x  =  \frac{ 5 \pm \sqrt{ 45} }{2}

The solutions are:

x  =  \frac{ 5  -  3\sqrt{ 5} }{2}  \: or \: x  =  \frac{ 5 +3 \sqrt{ 5} }{2}

The equation has no complex roots.
