Answer:
Step-by-step explanation:
y=m4+6n is the only expression that contains exactly two (2) terms
PREMISES
y=the expression that represents “a sum of exactly two terms” from the among the set (xy, m4+6n, 3+7s+t)
CALCULATIONS
The expression from among the set (xy, m4+6n, 3+7s+t) that represents exactly 2 terms can be denoted by the statement:
y=
m4+6n since the other expressions xy and 3+7s+t contain 1 term and 3 terms respectively.
