We already know 12 x 12 =144. So all you could do isis add 12 to 144 to get your complete answer. Which is:
12 x 13 = 156
I'm certain that part b is essentially the same question as a but it asks for the exact amount of difference in distance which is 28 kilometers. Your estimate would be reasonable since there is no major difference between the estimate and the actual difference.
The change represents decay and the percentage decrease is 2.9%
<h3>Exponential function</h3>
The standard exponential function is expressed as y = ab^x
where:
a is the initial
b is the rate
If the value of b is less than 1 hence the function is decay and if greater than 1, the function is growth
GIven the expoenential function y=100(0.971)^x
Since the value of b = 0.971 < 1, hence the function is a decay.
The percentage decrease = 1 - 0.971 = 2.9%
Hence the percentage decrease is 2.9%

Answer:
4
Step-by-step explanation:
-3/4m - 1/2 = 2 + 1/4m
The denominators are 4 and 2
If we multiply by the least common multiply we can get rid of the fractions
2 and 4 have a least common multiple of 4
Answer: $34.75
Step-by-step explanation:
n= 6.25x+3.50
n=6.25(5)+3.50
n=31.25+3.50
n=34.75
