Answer:
C. b=1053
Step-by-step explanation:
Isolate b:
- 0.25b+168.75=432
- Subtract 168, 0.25b=263.25
- Divide by 0.25, b=1053
Answer:
B. (x+4)(x+i)(x-i)
Step-by-step explanation:
Let
We can factor this polynomial by grouping:
We factor further to obtain:
We apply difference of two squares to get:
Yes, the partition gives the two brothers equal shares.
Step-by-step explanation:
Step 1:
Assume the entire field has an area of B. So one brother takes , , and
So we need to calculate how much this brother takes in terms of B.
To do this we calculate how much is.
Step 2:
To add ,
First take the LCM of the denominators 12, 6, and 4
The LCM is 12, we multiply the denominator to get the LCM value, this same value is multiplied to the numerator too.
Step 3:
One brother gets , so we need to calculate how much the other brother gets.
The other brother's share =
So both the brothers get equal shares
