A. Since the rectangle can hold about three of those circles on the side, the area is 5x12=60. And since it gives you have the area of the circle, multiply by 2 so it would be 8. Therefore, 8+8+60=76, so it is 76 cm in total.
B. Since the rectangle can hold about three circles on the side the area is 6x3=18. And since it gives you the area of half the circle, multiply it by 2 so it would be 4. Therefore, 4+4+18=26 cm in total.
C. Since the rectangle can hold about three circles on the side the area is 6x6=36. And since it gives you the area of half the circle, multiply it by 2 so it would be 4. Therefore, 4+4+36=44 cm in total

Finally, A. Since in the beginning you multiply 4 by 3. Therfore your answer which is 72 must be multiplied by 2. So the answer is 144.

B.Since in the beginning you multiply 2 by 3. Therfore your answer which is 26 must be multiplied by 2. So the answer is 52.

C.Since in the beginning you multiply 2 by 3. Therfore your answer which is 44 must be multiplied by 2. So the answer is 88.

In the Final analysis, A. 144 cm, B. 52 cm, and C. 88cm

What is the value of x in the equation 2(x – 3) + 9 = 3(x + 1) + x?<br>x = <br>​
sukhopar [10]

Start with

2(x-3)+9=3(x+1)+x

Expand both parentheses by multiplying both terms by the number outside:

2x-6+9 = 3x+3+x

Sum like terms:

2x+3 = 4x+3

Simplify the "+3" on both sides:

2x = 4x

Subtract 2x from both sides:

2x=0

Divide both sides by 2:

x=0
