Answer:
What is the coefficient of x in the expression 5x³ + 2y² – 5x + 7?
(c) -5
How many terms are there in the expression 5x+3y+8?
(c) 3
Explanation:
A coefficient is the number in front of the variable which in this case, the x has a 5 as its coefficient. I don't know if you meant "What is the coefficient of x in the expression 5x³ + 7x² – 5 ?" as a question as well, but if it was then the coefficient would be 0 since there is no x, only an x³.
Terms are "either a single number or variable, or numbers and variables multiplied together"
So this would make 5x+3y+8 have three terms: 5x, 3y, and 8
