What is the coefficient of the second term of the trinomial?

marin [14]

The coefficient of the second term is 18.

What you do is you FOIL the terms:
$(3x+3)(3x+3)\\ Multiply\ the\ first\ terms\ together:\\ 3x*3x=9x^{2}\\ Then\ the\ outer\ terms:\\ 3x*3=9x\\ Next,\ the\ inner\ terms:\\ 3x*3=9x\\ Finally,\ multiply\ the\ last\ terms:\\ 3*3=9\\ Putting\ the\ terms\ together:\\ 9x^{2}+9x+9x+9=9x^{2}+18x+9\\\\ Since\ (3x+3)^{2}=9x^{2}+Bx+9=9x^{2}+18x+9,\ then \ B=18.$

The two numbers are 31 and 35.

Step-by-step explanation:

Let,

one number = x

2nd number = y

According to statement;

x+y=66 Eqn 1

y=x+4 Eqn 2

Putting y=x+4 from Eqn 2 in Eqn 1;

$x+(x+4)=66\\x+x+4=66\\2x=66-4\\2x=62\\Dividing\ both\ sides\ by\ 2\\\frac{2x}{2}=\frac{62}{2}\\x=31\\Putting\ x=31\ in\ Eqn\ 2\\y=31+4\\y=35$

The two numbers are 31 and 35.
