Area of rectangle = x(x+2) = x^2 +2x
area of triangle = x*2/2 = x
so the shaded fraction of the rectangle will be x(x+2)/(x+2)=x
Answer:
Step-by-step explanation:
27π=120°/360°*πr^2
81π=Area of circle
Answer:
h=A-πr²÷2πr
Step-by-step explanation:
M making h subject
A=2πrh+πr²
A-πr²=2πrh
A-πr²÷2πr=h
h=A-πr²÷2πr
0.5s + 1 = 7 + 4.5s Subtract 4.5s from both sides
-4s + 1 = 7 Subtract 1 from both sides
-4s = 6 Divide both sides by -4
s = -

Simplify
s = -
