Answer:
4 cm
Step-by-step explanation:
Perimeter = 18cm
θ = 2.5 radian
s = rθ, s = Arc length
Perimeter of Sector, P = arc length, s + 2r
Perimeter = rθ + 2r
r = Radius
18cm = r(2.5) + 2r
18cm = 2.5r + 2r
18cm = 4.5r
r = 18 /4.5
r = 4
Answer: -1
Step-by-step explanation: Let the integer be x
It's additive inverse = -x
= x / -x = -1
Answer:
-3
Step-by-step explanation:
4(2)-2(2+4)+1=8-2(6)+1=9-12=-3
Answer:
The result will be: 5x³ -11x² -9x + 18
that would mean he's 7 right now
