Answer:
c = 4
See explanation
Step-by-step explanation:
Given:
4c = 3c - 4
Your calculation:
4c = 3c + 4
4c = 4 - 3c
4c = 1c
c = 4/1
c= 4
Correct calculation:
Collect like terms by subtracting 3c from both sides
4c - 3c = 3c + 4 - 3c
Check:
4(4) = 3(4) + 4
16 = 12 + 4
16 = 16
Therefore,
Your final answer is correct but your method of calculation is not correct
$3.296
Simple interest=PRT/100
P=Principal=$20.600
R=rate=8%
T=time=2yrs
=20.600×8/100×2
=$3.296
the answer would be 20% on the books
length= 5 + x
breadth = 6 + 2x
area = 30 + 16x + 2x^2
