Answer: 238.95 in²

because this is a regular pentagon

=> the area of the regular pentagon will be 5 times the area of the triangle in the picture.

we have: the area of the triangle is: (11,8.8,1)/2 = 47,79 (in²)

=> the area of the regular pentagon is 5. 47,79 = 238,95 (in²)

What number must be added to the expression below to complete the square? x^2+x. a.1/4 b.1/2 c.2 d.1
torisob [31]

Option a. 1/4 is the right answer

Step-by-step explanation:

Given expression is:

x^2+x

Here

we know that

a = x

In order to find the number which should be added

comparing with the formula

(a+b)^2 = a^2+2ab+b^2

2ab = x\\2.x.b = x\\b=\frac{x}{2x}\\b = \frac{1}{2}

So, we will add the square of 1/2 which is 1/4

Hence,

Option a. 1/4 is the right answer

I need this done by 9:30 please!!!<br><br> Solve:<br> x/3-1/2=5/6
3241004551 [841]

Answer:

x=4

Step-by-step explanation:

x/3-1/2=5/6

Add 1/2 to each side

x/3-1/2+1/2=5/6+1/2

x/3 = 5/6+1/2

Get a common denominator on the right

x/3 = 5/6+3/6

x/3 = 8/6

x/3 = 4/3

Multiply each side by 3

x/3 *3 = 4/3*3

x = 4

A full circle is 360 degrees.

The circle is separated into 8 parts, so each arc is 1/8 of a circle, which equals: 360/8 = 45 degrees.

There are 2 45 degree arcs between B and C, so the arc from B to C = 45 x 2 = 90 degrees.

The answer is B.
