Alarge multiplex movie house has many theaters. the largest theater has 44 rows. there are 20 seats in the first row. each row has four seats more than the previous row. how many total seats are there in this theater?

the answer is 192

Step-by-step explanation:

the reason its 192 is because you have 44 rows. the first row it tells you that you have 20 in it so how to find the total number or seats is this way 43×4+20 the reason you dont put 44+4 is because you already know the Frist row has 20 seats in it then you just add it in

center (1,3) with radius 6

step-by-step explanation:

we must complete the square to find the center and radius of the circle.

first make sure the x and y squared terms have 1 as their coefficients. we also make sure x and y terms together.

we now create space between the x and y terms with parenthesis.

we complete the square by taking the middle terms -2x and the -6y - divide each and square them.

we add the squares to both sides.

simplify.

and write the quadratics in factored form.

the center is (h,k) or (1,3). the radius is the square root of 36 which is 6.
