State the factoring rule for difference of two squares a2-b2

Mathematics

<h3>Answer:  a^2 - b^2 = (a-b)(a+b)</h3>

The order of the factors does not matter.

So (a-b)(a+b) is the same as (a+b)(a-b)

This is known as the difference of squares factoring rule.

You can FOIL out (a-b)(a+b) and you'd get a^2+ab-ab-b^2. Note how the ab terms cancel leaving us with a^2-b^2. This confirms we have the correct factorization.

rohan bought 3.4 pounds of cashews on wednesday 2.5 pounds on thursday and 4 pounds on friday. he is going to divide them equall
kenny6666 [7]
First, you would add all the pounds he bought altogether, to know how much he bought, and how many pounds he will divide amongst his friends. That's 3.4 + 2.5 + 4 which equals to 9.9.

So he divides 9.9 pounds of cashews between himself and his two friends, and that makes it dividing 9.9 pounds between two people. That would simply make it : 9.9 ÷ 3, which equals to 3.3

Each friend will get 3.3 pounds of cashews.

Find an explicit rule for the nth term of the sequence.
Sphinxa [80]

Step-by-step explanation:

in a geometric sequence there is a constant factor x that is multiplied with every previous term to create the next one.

a2 = 20

a5 = 1280 = a2×x×x×x = a2×x³ = 20x³

64 = x³

x = 4

=> a1 = 5

therefore

an = an-1×4 =

a1 \times  {4}^{n - 1}

n > 1
