Quick computings cost function will take the form of a quadratic function c(x)=0.5x^2-10x+100. find the quick computings cost of producing 25 calculators by substituting x=25 into the cost function

okey so the slope is -3/5 and the y -intercept is 7/5

hope this if needed hmu

first the equation needs to be simplified. so the equation would now look like:   52-24+11

then you multiply.

and when you multiply, you will get the answer of 39.  

dont't really have enough info here but its likely

sss for the three sides being congruent ( its stands for side side side)

or

sas   for side angle side.   so a side is congruent and and angle and a side
