Answer: 2.12 × 
The coefficient (in green) will be 2.12
Step-by-step explanation:
Scientific notation is written by multiplying the number by a power of 10. This number is a number between 1 and 10.
Since this is a smaller number, we will be multiplying it by a power of 10 to a negative number.
To get this value to a number between 1 and 10, we must multiply it by 10 3 times (also shown as 10³) which gives us 2.12.
To get back to the original value, we multiply this by
. This gives us our answer.
Anything multiplied by zero is zero
A) John: 3.75+1.45m
Kiara: 6.25+0.55m
B) (3.75+1.45m)+(6.25+0.55m)
Added: 10+2m
C) (10+2m) divide by 2
Factored: 5+m
Plug in -1 for x the solve the equation. 3 * -1 -4(-1) which equals 7
