Consider the following expression 9x+4y + 1 Select all of the true statements below 1 is a constant. 9x and 1 are like terms. 9x is a factor, 9x + 4y + 1 is written as a sum of three terms. ( 9x is a coefficient. None of these are true.

ANSWER:
1st option: 1 is a constant
4th option: 9x + 4y + 1 written as a sum of three terms
STEP-BY-STEP EXPLANATION:
We have the following equation:
[tex]9x+4y+1[/tex]From the following equation we can say the following:
• The only constant term is 1
,• None of the terms are similar
,• There are a total of 3 terms
,• The coefficients are 9 and 4
,• The factors are 9, 4, 1, x and y
From the above we can affirm that the true statements are:
• 1 is a constant
• 9x + 4y + 1 written as a sum of three terms
