the Rodriguez family buys four adult tickets for senior tickets and five children tickets to the aquarium. The expression 4(a+12)+5(8) represents the total cost of the tickets.

See Explanation

Step-by-step explanation:

You didn't really say what you want to calculate but based on the information, I'll assume that you want to calculate the total cost.

Since he expression 4(a+12)+5(8) represents the total cost of the tickets. Therefore, the total cost will be:

= 4(a+12)+5(8)

= 4a + 48 + 40

= 4a + 88

the answer would be d.

step-by-step explanation:

move all variables to the left side and all constants to the right side

(x−3)^2+(y−1)^2=16

this is the form of a circle. use this form to determine the center and radius of the circle.

( x − h ) 2 + ( y − k ) 2 = r 2

match the values in this circle to those of the standard form. the variable   r   represents the radius of the circle,   h   represents the x-offset from the origin, and   k   represents the y-offset from origin.

r = 4

h = 3

k = 1

the center of the circle is found at   ( h , k ) .

center:   ( 3 , 1 )

these values represent the important values for graphing and analyzing a circle.

center:   ( 3 , 1 ).

radius:   4
