Identify the terms and like terms in the expression. 1: 11x + 2x

2: 9x - 5x

3: 21x + 6 - x - 5

4: 8x + 14 - 3x + 1

1. The like terms are 11x and 2x and the terms are 11x and 2x

2. The like terms are 9x and -5x and the terms are 9x and -5x

3. the like terms are (21x and x) and (6 and -5) and the terms are 21x, 6, -x, and -5.

4. The like terms are (8x and -3x) and (14 and 1). And the terms are 8x, 14, -3x, and 1.

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.
