Answer:
80.56
Step-by-step explanation:
To find the rectangle area you just multiply its length by its width:
17 * 4 = 68
You have to sum two semicircles on top of that. Since it is 2 semicircles you can just calculate one circle. Using the circle area formula: 
Since the radius (r) is 2 and
is 3.14, you have the following equation:
A = 3.14 * 2² ==> A = 3.14 * 4 ==> A = 12.56 <em>(A is Area)</em>
Sum the rectangle's area with the circle's area:
12.56 + 68 = 80.56
And vuoila! there's your answer.
Answer:
3x + 2 =2x 3x = 2x - 2 3x - 2x = -2 x = -2 Proof: 3 * -2 + 2 = 2 * -2 -4 = -4
