Astudent is attempting to isolate the variable s in the literal equation below. which statement best applies to the sample mathematical work shown?
given: st + s – 3 = 5 – s

a.
the student failed to add the proper quantity in step 1.
b.
the student failed to divide both sides by s properly in step 2.
c.
the student failed to subtract t from both sides properly in step 3.
d.
the mathematical work is correct as written.

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.

idk the answer i want to say 10 but then it would be equal so try 9 but then yeah so yeah we love edgen
