A team is playing a game and currently has 43 points. If they lose 56 points and then gain 13 points, what will their score be? Write an expression that models this situation and evaluate the expression.

(43 - 56) + 13 = 0 points

Step-by-step explanation:

We start with 43 points and loose 56 -- 43-56

then, 13 points are gained = (43 - 56) + 13

simplify and solve:

-13 + 13 = 0

*Note: you can write the expression without the brackets

hello from mrbilldoesmath!

answer:   x^2 + y^2 = 1024

discussion:

the equation of a circle with center (h,k) and radius "r" is

(x-h)^2 + (y-k)^2 = r^2.

in our case

(x-0)^2 + (y-0) ^2 = 32^2 = 1024

you,
