X=22
Area is found by multiplying (x+7)and (2x-1) together. 22+7=29, 2(22) -1 = 43, 43+29=72
In the year 2009 there were 3500 birds on an island. If the bird population is declining 2.2% per year it means that in the year 2014 we will have 3500*

= 3131.57 birds.
The best prediction is that in the year 2014 the bird population will be 3132.
I would guess that you would need to find the Least Common Multiple (LCM) of 99 and 24 first.
After listing out all of the multiples, you would have 792 be the LCM of 99 and 24. But since we need to find the integer value of n, in 99n (which means 99 x n), then we need to divide 792 by 99, which would be 8.
n = 8
1/3s = 1/5
Multiply by the reciprocal.
1/3 * 3/1 = 1/5*3/1
1/5 * 3/1 = 3/5
s = 3/5
Answer: s = 3/5
Answer:
x = 20°
Step-by-step explanation:
4x + 10 = 90
4x = 80
x = 20
