Answer:
147
Step-by-step explanation:
start by multiplying 42 and 7=294
now divide that by 1/2 =147
Answer:
2080.69
Step-by-step explanation:
Answer:
x = −37/16
This is the value of x which completes the equation properly, unless you mean x^2 instead of x2.
Solution
To find out which expressions represent the difference of exactly
two expressions
a) 6(x+7) - 2
This can be simplified as
6x + 42 - 2
6x + 40
Clearly this does not represent difference of the two
expressions .
b) -2j
Clearly this represents a single expression , this does not represent
a difference of 2 expression .
c) 4f - 2g
Here we have 2 different expressions 4f and 2g
Difference of these 2 expressions are 4f - 2g
Hence , this option represent difference of exactly two
expression
d) 3xyz - 10
3xtz - 10 represnts a single expression
Here we have a single expression
Therefore it does not represent difference of exactly 2
expression .
