Pryia is simplifying the expression-2(4 - 2x) - 3 -2x. Here is her work: -2(2 - 2x) - 3 - 2x
-8 - 2x - 3 - 2x
-11 - 4x

Pryia’s work is incorrect. Explain the error she made.

Write a expression equivalent to -4(x + 3) - 12x + 5 that only has two terms.

George has seven boxes of five pencils. giulio three boxes of eight pencils. one of the boys arranges all his pencils equally into two groups. was this george or giulio how many are in each group explain

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.

If 2(a^2+b^2)=(a+b)^2 then, > a+b=0, > ab=0, > a=b, > 2a=b
