Answer:
17 > x+1
Step-by-step explanation:
You can add or subtract any number from both sides to get an equality with the same meaning:
17 > x+1
0 > x-16
You can multiply or divide by any number (except division by 0) to get an equality with the same meaning. If the multiplier (or divisor) is negative, the comparison changes direction.
-16 < -x
48 > 3x
The triangle on the left side has two legs of length 4 m and 6 m. It's a right triangle, so the hypotenuse has length √((4 m)² + (6 m)²) = 2√13 m. Only the 4 m leg and the hypotenuse count towards the shape's overall perimeter.
The rectangular part contributes 9 m from the top side and 9 m from the bottom one, thus a total of 18 m.
The half-circle has diameter 6 m (indicated by the dashed line, same as the height of the triangle on the left). A full circle with diameter <em>d</em> has circumference <em>πd </em>; a half-circle with the same diameter would then contirubte <em>πd</em>/2, or in this case, 3<em>π</em> m.
So, the total perimeter of the shape is
(4 m + 2√13 m) + 18 m + 3<em>π</em> m ≈ 38.6 m
