Mathematics

Multiply 9 inside the terms:
So we get: 9x+9 = 25+x
Moving X from the other side to the 9x side, so it changes the sign from + to -
9x-x = 25-9
So, 8x = 16
X= 16/8
Therefore, X=2 is the answer

Multiplying as indicated, 9x + 9 = 25 + x

Combining the x terms:  8x + 9 = 25
Combining the constants, 8x = 16.  
Solving for x, x = 16/8 = 2 (answer)

Plsss help. Thanks!!

Answer:

401

Step-by-step explanation:

1. Approach

To solve this problem, one first has to think about the given figure in a certain way. In the figure, one can see that it is a circle attached on either side of a rectangle. To find the perimeter of the figure, one has to find the circumference of the circle and then add two sides of the rectangle to the answer

2. Circumference of the circle

The formula to find the circumference of a circle is;

2r(pi) or d(pi)

~ diameter times the value (pi)

Normally to find the circumference of a semicircle, one would have to divide this formula by 2, but since in this case, one has to add two congruent semicircles, so therefore, the effect of dividing the equation by two, only to multiply by two again cancels, and hence, there is no need to divide by 2.

Substitute in the values;

(78)(pi)

~ 245

3. Find the perimeter of the entire object

Now, one has to add the two additional sides of the figure, to the circumferences of the semicircles to get the final answer;

78 + 78 + 245

= 401
