Hello im Esmerallda
How are u
its d, I just solved it...
Answer:
the number before the first variable (first term)
Step-by-step explanation:
this appears to be an incomplete question. The numerical coefficient of a term is the number before the variable.
the constant is the number without a variable.
Answer:
let second side be x
then first side = x-13
third side= x+1
now
perimeter of triangle = 45
x-13+x+x+1=45
3x=57
x=19
first side = x-13= 19-13=6
third side= x+1=19+1=20
Step-by-step explanation:
The mistake is there is no parenthesis around 4x+12
