Answer:
4.76cm
Step-by-step explanation:
Given data
circumference= 15cm
The expression for circumference is
C= 2πr
substitute and solve for r
15= 2*3.14*r
r= 15/ 2*3.14
r=15/ 6.28
r= 2.38 cm
Hence the diameter is
D= 2r
D= 2*2.38
D=4.76cm
The correct answer would be B

(x-5) (x+4)
x^2-x-20
What two terms multiply to -20 and add to -1
-5*4 = -20
-5+4 = -1
2(k-5)+3k=k+6
-3k. -3k
2(k-5)=-2k+6
/2. /2
k-5=-k+3
+k. +k
2k-5=3
+5. +5
2k=8
k=4
