Answer:

(10x + 8y)(10x - 8y)

Step-by-step explanation:

The given expression is 100x^2 -64y^2

100 can be written as 10^2

64 can be written as 8^2

100x^2 - 64y^2  = (10x)^2 - (8y)^2

We know that a^2 - b^2 = (a +b )(a - b)

Applying the formula, we get

(10x)^2 - (8y)^2 = (10x + 8y)(10x - 8y)

Answer: (10x + 8y)(10x - 8y)

Thank you.

-Dominant- [34]

Answer:

5.6

Step-by-step explanation:

Given :

Quality rating for 8 movies :

5.6, 7.9, 7.0, 5.9, 7.8, 6.2, 6.4, 5.2

Let rating for the 9th movie = x

Average quality rating olfor the 9 movies = 6.4

To find x :

Sum of all ratings / number of ratings = 6.4

(5.6 + 7.9 + 7.0 + 5.9 + 7.8 + 6.2 + 6.4 + 5.2 + x) / 9 = 6.4

(52 + x) / 9 = 6.4

52 + x = 57.6

x = 57.6 - 52

x = 5.6
