Please Please Please Help! This equation shows how the total length Anna has knit depends on the number of nights she has spent knitting.

t=34n+48

The variable n represents the number of nights Anna has spent knitting, and the variable t represents the total length she has knit in centimeters.

How many nights did she spend knitting if her scarf measured 184 centimeters in total?

c.   x=2.4cm

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.

the correct answer is the last option
