The places that I have "the square root of" you must replace it with the square root sign. I'm using my phone so I wasn't sure how to insert a square root sign.
P = s + (s + 5) + (s + 5) This represents the two sides that are 5 inches longer than the base (s + 5) and the base (s). Simplifying. 100 = 3s + 10 subtract 10 from both sides 90 = 3s divide both sides by 3 30 = s base = 30 sides = 35
Well in the first equation m= -17 So you just have to substitute -17 in and see if it makes sense like with the first equation -17 + 25 does equal 8 therefore x (in the second equation) = m (in the first)
