The answer is B.
The reason behind it being that since the sides of the entire patio are given, you can multiply them and get the area of the entire patio, then you can subtract the area of the bench, which in this case is 12 because 2 times 6 is 12. Since you can’t solve for (x+20) or (x+10), you can multiply them by themselves. This would give you the equation (x+20)(x+10)-12.

Half is a third of it.what is it?

Sati [7]

Let's call 'it' x. 1/2 is equal to one third of x, so we could say that 1/3x = 1/2

Now we just have a simple equation to solve:

1/3x = 1/2
x = (1/2) / (1/3)

Dividing by a rational number (such as 1/3, which is expressed in fraction form) is the same as multiplying by its reciprocal (the reciprocal of a fraction is itself when the numerator and denominator have been swapped). Therefore

x = (1/2) / (1/3) = (1/2) * 3 = 3/2 = 1.5

To check this answer, test the statement. Half is a third of x, where x=1.5:

1.5 / 3 = 0.5 = 1/2

Anyone want to answer the number for X???????

Anna007 [38]

Answer:

$\frac{\sqrt{10} }{2}$

Step-by-step explanation:

Using cosine (since that is adjacent over hypotenuse), cos(60)=1/2 so your answer is hypotenuse*1/2= $\sqrt{10}*\frac{1}{2}=\frac{\sqrt{10} }{2}$
