Answer:

5(x+2)(x-2)

Step-by-step explanation:

Find the greatest common factor (GCF) of the 2 terms:

GCF is 5.

Factor out the GCF:

5x^2-20\\5(\frac{5x^2}{5} -\frac{20}{5} )\\5(x^2-4)

Rewrite as a difference of squares (a^2-b^2=(a+b)(a-b)):

5(x^2-2^2)\\5(x+2)(x-2)

Find the sum of this infinite geometric series where a1=0.3 and r=0.1
ratelena [41]

Answer:

1/3

Step-by-step explanation:

The formula for computing the sum of an infinite geometric series is

S=\frac{a_1}{1-r} where r is between -1 and 1 and r is the common ratio, and a_1 is the first term of the series.

So let's plug in:

S=\frac{0.3}{1-0.1}

S=\frac{0.3}{0.9}

S=\frac{3}{9} I multiplied bottom and top by 10.

S=\frac{1}{3} I divided top and bottom by 3.

The sum is 1/3.
