State the factoring rule for difference of two squares a2-b2
ludmilkaskok [199]
<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.

Anuta_ua [19.1K]

Answer:

The unit rate is 20.8 ft/ sec.

Step-by-step explanation:

It is given that the displacement of 644.8 ft in 31 s.

When the rate is define in the quantity of 1, then it is called unit rate.

In 31 s the displacement is 644.8 ft.

31 \text{ s}=644.8 \text{ ft}

Divide both sides by 31,

\frac{31}{31} \text{ s}=\frac{644.8}{31} \text{ ft}

1 \text{ s}=20.8 \text{ ft}

For one second the value of the displacement is 20.8.

Therefore the unit rate for 644.8 ft in 31 s is 20.8 ft/sec.
