Given functions are


The total number of ducks and swans in the lake after n months can be determined by adding the functions s(n) and d(n).





Taking 2 as common, we get

Hence The total number of ducks and swans in the lake after n months is
Simple problem:
When simplifying 3(x-6) they subtracted 3 instead of multiplied by 3.
3(x-6) should be 3x-18.
Now when you simplify:
3x-18+4x+12-6x
Which is x -6 =0
Or x =6
Answer:
Integers, Real numbers, Rational Numbers and, Whole numbers.
Btw all whole numbers are integers because an integer is any whole number that's not a fraction or anything other than a whole number.
Step-by-step explanation:
It's not irrational because those have pi in them or go on and on.
Answer:
solve for x
4x-6=26
4x=26+6
x=32/4
x=8
area of rectangle=l*b
=26*14
=364
area of triangle=b*h/2
=18.4*20.4/2
=375.36/2
=187.68 m^2
for another side of a triangle
(18.4)^2+(20.4)^2=c^2
338.56+416.16=c^2
=c
27.47=c
27.5=c
now, perimeter of triangle=a+b+c
=27.5+18.4+20.4
=66.3 m^2
radius=diameter/2
=26/2
=13 ft
diameter=26 ft
circumference=2πr
=2*3.14*13
=81.64
Area of a circle=π
=3.14*(13)^2
=3.14*169
=530.66 ft^2
Step-by-step explanation:
Sum of all interior angles on a polygon is
180( n - 2) n = number of sides in the polygon.
now, this one is is a 21-gon, thus the sum is 180( 21 - 2).
