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

T=60+7x
x is for numbers of hours worked
t stands for total pay
Answer:
y = x^2 +8x +16
Step-by-step explanation:
t can be written in terms of x, then substituted into the equation for y.
x = t -4
x + 4 = t
y = t^2 = (x +4)^2
y = x^2 +8x +16
