Answer:
31, 33, 35
Step-by-step explanation:
Let 2n+1 be the first odd number. What will the next one be? Add two:
Let 2n+3 be the next odd number. Again, what is the next one? Add two:
Let 2n+5 be the third odd number.
The sum of those three numbers must be 99. You don't have to have the parenthesis here, but I think they help clarify where everything comes from.
(2n+1) + (2n+3) + (2n+5) = 99
Add like terms, and solve for n:
6n + 9 = 99
6n = 90
n = 15
The three odd numbers we want are:
2(15)+1 = 31
2(15)+3 = 33
2(15)+5 = 35
Double check: 31+33+35 = 99?
The coefficient of the xy term when the expression is multiplied out
and the like terms are collected is zero
Step-by-step explanation:
There two binomials we need to multiply them
The steps of multiplying two binomials
1. Multiply the first terms
2. Multiply the second terms
3. Multiply the 1st tern in the first bracket by the 2nd term in the
second bracket
4. Multiply the 2nd tern in the first bracket by the 1st term in the
second bracket
5. Add the like terms
In (ax + by)(cx – dy)
∵ (ax)(cx) = ac x²
∵ (by)(-dy) = - bd y²
∵ (ax)(-dy) = - ad xy
∵ (by)(cx) = bc xy
- Then like terms are (- ad xy) and (bc xy) add them
∵ (- ad xy) + (bc xy) = (-ad + bc) xy
∴ The coefficient of the xy term is (-ad + bc)
∵ ad = bc
- Replace ad by bc in the bracket above
∴ The coefficient of the xy term = (-bc + bc)
∴ The coefficient of the xy term = zero

Answer is 6 kg:
Given that Adam was asked to post a parcel. The weight of the parcel was 12 lbs and 8 oz.
To convert the weight in kgs:
Let us convert oz into pounds first to make it uniform.
We have 16 0z. = 1 lb
Hence 8 oz. = 8/16 = 0.5 lbs
Weight of the parcel = 12.5 lbs.
We have the converting factor as
2.2 pounds make 1 kg.
Hence 12.5 pounds = 12.5/2.2 = 5.6818
So weight of the parcel in kg= 6. (after rounding off)
