Which expression is a difference of squares with a factor of 5x − 8? 25x2 − 16 25x2 16 25x2 − 64 25x2 64.

SpyIntel [72]

The product of the factors (5x − 8) and (5x + 8) is 25x² − 64. Then the correct option is C.

<h3>What is polynomial?</h3>

Polynomial is an algebraic expression that consists of variables and coefficients. Variable are called unknown. We can apply arithmetic operations such as addition, subtraction, etc. But not divisible by variable.

One factor of the polynomial is given which is 5x − 8.

Then the polynomial will be

Let the other factor be 5x + 8

Then their product will be

(5x − 8)(5x + 8)

(5x)² − 8²

25x² − 64

At the city museum, child admission is $5.20 and adult admission is $8.30 . On Monday, three times as many adult tickets as chil

harkovskaia [24]

Let # of child tickets = c
# of adult tickets = 3c
3c (8.30) + c (5.20) = 1173.90
24.9c + 5.2c = 1173.90
30.1c=1173.90
c=39 tickets
3c=39x3= 117 tickets
Therefore, 39 child tickets and 117 adult tickets were sold on monday, thus, a total of 156 tickets were sold.
