Question 18 find the sum in reduced form. 2 5 + 2 3

Step-by-step explanation:

Those are fractions, are they not? I'll treat them that way.

Find the lowest common denominator.

You need 1 three and 1 five.

2/5 = (2*3)/(5 * 3) = 6 / 15

2/3 = (2*5)/(3*5) = 10 /15

  Just add the numerators.

It is reduced. There are other ways to write it

16/15 = 1 1/15 is one of them

13

step-by-step explanation:

divide the cost of the total of sodas you bought by the cost of one soda, for example:

$24.57 divided by $1.89 is 13 which means you bought 13 sodas

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.
