Maricella solves for x in the equation 4 x minus 2 (3 x minus 4) + 4 = negative 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?

Step-by-step explanation:

Given the equation

4x-2(3x-4)+4 = -x+3(x+1)+1

Open the parenthesis on both sides

4x-6x+8+4 = -x+3x+3+1

-2x+12 = 2x+4

Collect like terms

-2x-2x = 4-12

-4x = -8

Divide both sides by -4

-4x/-4 = -8/-4

x = 2

Hence the value of x is 2

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.
