Answer:
-17.5 degrees Celsius in 5 hours
Step-by-step explanation:
0(current temp)-3.5x(temp decrease)=5(hours)
then simplify
12+20•3-3x-15
multiply the numbers : 20•3 = 60
12+60-3x-15
group like terms
-3x+12+60-15
add and subtract the numbers : 12+60-15=57
final answer = -3x+57
Simplify the expression 5(x-3)(x^2+4x+1)
it would be I think answer number 3
The function rule is -1/5
