Answer:
-x^2+15x+2/x
Step-by-step explanation:
Hope this helped............if any trouble ask me
X+y+z = 132
x = 7+z
y = 3z
(7+z)+3z+z = 132
5z = 132-7
z = 125/5
z = 25 <=====
x = 7+z
x = 7 + 25
x = 39 <=====
y = 3z
y = 3 × 25
y = 75 <=====
hope it helps :)
Answer:
72.22 inches
Step-by-step explanation:
Okay so the formula for circumference is C=2πr so since the diameter is twice the radius, the radius is 11.5. Now you have to multiply 11.5 and 2. That equals 23. Now you have to multiply 23 by π which is about 3.14. 23 times 3.14 is 72.22 inches.
Hope this helped!! :D
