-2 + 4i + 1 - 7i + 8 - 5i
7 - 8i
Answer:
b=9
Step-by-step explanation:
move the constant to the right which makes it 8b +5.04=77.04
then subtract 77.04 - 5.04 which = 8b = 72

Required equation to determine two consecutive even number is 
and required numbers are 4 and 6.
<u>Solution:</u>
Given that product of two consecutive positive integer is 14 more that their sum. Need to create the equation and solve it to get two numbers.
Let’s assume first even number be represented by x.
So second consecutive even number will be 
Sum of two consecutive number = 
Sum of two consecutive number = 
Product of two consecutive number = 
Product of two consecutive number is 14 more that sum of two consecutive numbers, so if we subtract 14 from product, we will get sum.
One even number = 
Other even number = 
Hence required equation to determine two consecutive even number is 
and required numbers are 4 and 6.
Whole numbers are number like 1 ,2 ,3 or ,1.0 ,2.0 , or 3.0
decimals are 2.46, 0.73 or 6.89
whole numbers do not have a digit past the decimal place
decimals do
