I think it belongs to irrational.
Answer: 21 +4c
Step-by-step explanation:
I don’t think you posted a picture along with this so I can’t answer
P- pineapple
p-pear
m-mango
a-apple
a=4*m
p=2*a
P=m
8 Pineapples.....8 mangos
a=4*m= 4*8=32 apples
p=2*a=2*32=64 pears
You said that 8c + 5 = 4c - 11
Subtract 4c from each side: 4c + 5 = - 11
Subtract 5 from each side: 4c = - 16
Divide each side by 4 : c = - 4
