Answer:
Step-by-step explanation:
Mathematical expressions are expressions which are combinations of constants, variables and mathematical operations . A constant is a symbol in maths which has fixed numerical value for example 2 , 3, -6, [tex]\frac{2}{3}[/tex] are constants .A variable is a symbol in algebra which takes various numerical values and has no fixed value . Mathematical operations include [tex]+,-,\div ,\times[/tex].
By term word phase, we mean mathematical expression using constants and variables.
Given: 49 + m
Word Phase:
Sum of 49 and m
Here, 49 is a constant
m is a variable
+ is a mathematical operation.
