Combine like terms
2x - 5 + 29 + 4x + 6 - x

5x + 30

Step-by-step explanation:

Like terms are the terms that carry the same variable.

Here, 2x, 4x, and -x all have an x of degree 1. So, they are like terms. Thus, we can combine these into: 2x + 4x - x = 5x.

Now, -5, 29, and 6 are like terms because they are all constants, or non-variables. So, we can combine these: -5 + 29 + 6 = 30

Thus, the answer is 5x + 30.

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.
