How many terms are in the expression 4a'b - 5ab2 + 1? a) 3 b) 5 c) 7 d) 9

A, 3

Step-by-step explanation:

A term can be a constant or a variable or both in an expression.

In this expression we can consider 4ab, 5ab^2, and 1 to be terms.

answer: the answer is one of

step-by-step explanation:   we are given to write a proper fraction where the whole is divided into an even number of equal parts less than ten, and an odd number of those parts exist.

an even number less than 10 may be one of 2, 4, 6 or 8. so, the whole may be one of these four evens.

now, an odd number of these parts must exist, so the numerator must be an odd number, one of 1, 3, 5 or 7. it cannot be 9 because then the fraction will become improper.

thus, our fraction may be one of the following

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.
