i cant figure out the two left
Let's make the first even integer m and the second even integer n. The square of the first, decreased by the second is 130 is:

-n=130 ---> Add n to each side

=130+n ---> Take the square root of each side
m=±

Let's look at the first square number above 130, which is

. <em>m</em> is 12, therefore the next consecutive even integer is 14.

=144
144-14=130
The two consecutive integers are 12 and 14

Answer:
68%
Step-by-step explanation:
Mean = 25
Standard deviation = 5
The percentage of trees between 20 and 30
20 trees = 1 standard deviation below the mean ; mean - 1(standard deviation)
25 - 5 = 20
30 trees = 1 standard deviation above the mean ;
Mean + 1(standard deviation) ;
25 + 5 = 30
This means, 20 and 30 lies ±1 standard deviation from the mean which according to the empirical rule is 68%
According to the empirical rule :
