If I am reading the question correctly it would come out to -6x+42 First do all the addition and squaring, then factor in that negative. You come out to -2x^3 +2x^3-4x-2x+25+5+9+3. The x^3's cancel, the -x's add to -6x, then all that other adds to 42.
Answer:
no 146.5 > 145
Step-by-step explanation:
The answer would be 54 since there is only 180 degrees in a triangle so you subtract 90 and 36 from 180. You get 54
Price =x
x=30
half of 30 is 15
add 15 to 30
get 45 do that but change you're numbers
