A contractor bought 10.8 ft2 of sheet metal. He has used 4.9 ft2 so far and has $177 worth of sheet metal remaining. The equation 10.8x - 4.9x = 177 represents how much sheet metal is remaining and the cost of the remaining amount. How much does sheet metal cost per square foot?

i think c. but don't trust it.

step-by-step explanation:

answer: -2+√x,-2-√x

i hope this , i don't know if you're looking for a pair or not.

the square root of what number? if you add that, then someone will probably answer the question.

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.
