Step-by-step explanation:

Or area equals pi times radius squared
Answer:
x=44
Step-by-step explanation:
By the exterior angle theorem, we know that
x+4+82=3x-2
simplify
x+86=3x-2
subtract x from both sides
86=2x-2
add 2 to both sides
88=2x
divide 2 from both sides
44=x
They want you to find the composite function and they evaluate it at a give value for x...first the composite function...
f(g(x))=(x-1.5)^2+3(x-1.5)+6
f(g(x))=x^2-3x+2.25+3x-4.5+6
f(g(x))=x^2+3.75, this is the completed composition function...now:
f(g(1)=1+3.75=4.75
16 : 80
x : 100
Cross multiply.
80× = 100×16
× = 100 × 16 /80
× = 20 grams.
