Use the distributive property to find an equivalent expression for each of the following: a. 3(x + y) b. −(2x + 1) c. −4(x + 3y)

Find the solutions for a triangle with a =16, c =12, and b = 63º

Find the constant of variation for the relation and use it to write an equation for the statement. then solve the equation.

Girardo is using the model below to solve the equation . girardo uses the following steps: step 1 add 4 negative x-tiles to both sides step 2 add 1 negative unit tile to both sides step 3 the solution is which step could be adjusted so that gerardo's final step results in a positive x-value? in step 1, he should have added 4 positive x-tiles to both sides. in step 1, he should have added 3 negative x-tiles to both sides. in step 2, he should have added 4 negative unit tiles to both sides. in step 2, he should have added 1 positive unit tile to both sides.
