While catching fireflies, you and a friend decide to have a competition. After m minutes, you have (3m+13) fireflies and your friend has (4m+6) fireflies. Write an expression in simplest form that represents the number of fireflies you and your friend caught together.

7m+19

Step-by-step explanation:

If you are trying to figure it out only for that minute, you would get 7m+19 by first adding 4m and 3m and then adding 13+6. If you add those, you get 7m and 19. Combine them and you get 7m+19

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.
