It's impossible for the perimeter to be 28cm because the side lengths are greater that 28cm.
Answer:
10 ^(R-15)/3 -2= a
Step-by-step explanation:
R = 3 log (a+2) +15
Subtract 15 from each side
R-15 = 3 log (a+2) +15-15
R-15 = 3 log (a+2)
Divide each side by 3
(R-15)/3 = 3/3 log (a+2)
(R-15)/3 = log (a+2)
The opposite of log is to raise each side to the power of 10
10 ^(R-15)/3 = 10 ^ log (a+2)
10 ^(R-15)/3 = (a+2)
Subtract 2 from each side
10 ^(R-15)/3 -2= (a+2-2)
10 ^(R-15)/3 -2= a

Step-by-step explanation:
First no. is 12
Second no. is 8
Third no. of 25
Way 1 of grouping the numbers,
(12×8)×25
We can use associative law of multiplication as follows :
(a×b)×c = a×(b×c)
(12×8)×25 = (96) × 25
= 2400
Way 2,
12×(8×25) = 12 × 200
= 2400
Way 2 is easier to simplify because when we multiply 8 and 25, we get 200. It is very easy to multiply any number with a number that have zeroes. As a result we easily get the answer i.e. 2400.
74,000 / 500 = 148 months or 12 years and 4 months
