Leah scored p points in the first half of the basketball game. In the second half, she scored 3 more
the number of points she scored in the first half of the game. Altogether, she scored 21
points in the game. The following equation represents this situation where p represents the number
of points Leah scored in the first half.
How many points did Leah score in the first half?
a. 6
b. 9
c. 12
d. 18

both equations and proportions are better.

the line of

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.

127

whether it's diameter, or radius, i believe if i remember correctly from school, every amount has to always add up to 180. so if you take 53, and starting adding, long story short, taking 127 and adding it to 53, gives you 180.
