Maricella solves for x in the equation 4x-2(3x-4)+4=-x+3(x+1)+1 . she begins by adding –4 + 4 on the left side of the equation and 1 + 1 on the right side of the equation. which best explains why maricella’s strategy is incorrect?
the multiplication that takes place while distributing comes before addition and subtraction in order of operations.
in order to combine like terms on one side of the equation, the inverse operation must be used.
when the problem is worked in the correct order, the numbers that maricella added are not actually like terms.
maricella did not combine all three constants on both sides of the equation; she combined only two.
can you me

Kayla wants to find the width, ab, of a river. she walks along the edge of the river 65 ft and marks point c. then she walks 25 ft further and marks point d. she turns 90° and walks until her location, point a, and point c are collinear. she marks point e at this location, as shown. (a) can kayla conclude that δ and δ are similar? why or why not? (b) suppose de = 15 ft. what can kayla conclude about the width of the river?
