Y=-11. 2×-4 is -8, and -8-3 is -11.
This is an scalene triangle because a scalene triangle has no equal size
The perimeter of the composite shape is: (3π + 12)mm
<h3>What is a semicircle?</h3>
A semicircle is a part of a circle cut through its diameter.
Analysis:
perimeter of a semicircle = πr
where r = 6/2 = 3mm
perimeter of a semicircle = π(3) = 3π
perimeter of incomplete rectangle = L+2B, L = 6mm, B = 3mm
perimeter of rectangle = 6mm +2 x 3= 12mm
perimeter of shape = (3π+12)mm
In conclusion, the perimeter of the rectangle is (3π+12)mm

Answer: -0.5
<u>Step-by-step explanation:</u>
the x-value for A is 0.
the x-value for B is -2.
The total distance from A to B is -2.
= -0.5
A + -0.5
= 0 - 0.5
= -0.5
