The correct answer is -163
Explanation:
First you calculate within the parentheses; (8+4)= 12: 5-7*12*2
Next you multiply and divide; 7*12 is 84*2 is 168
Then you add and subtract; 5-168 is -163

Answer:
4 is the diameter
Step-by-step explanation:
Given:
C = 4π
Formula for circumference:
C = 2πr
Work:
C = 2πr
4π = 2πr
r = (4π)/(2π)
r = 2
Diameter:
d = 2r
d = 2(2)
d = 4
20; make both equations equal so whatever you plug in for x will be the same
2(4x+10)=8x+k
8x+20=8x+k
k=20
