You have to combine like terms.
Like terms are those with the same letters raised to the same power.
These are the sums of the like terms:
1) 4y^2 + y^2 + 14y^2 = 19y^2
2) - 3y + 4y - 7y = - 6y
3) - 6 - 2 = - 8
Simplified expression: 19y^2 - 6y - 8<------------ answer
Answer:
The difference in weights = pounds
Step-by-step explanation:
"DIFFERENCE" means to subtract their weights. We will subtract lesser amount from the greater amount to get our answer.
Also, we need to first make these mixed numbers into improper fractions by using the rule below:
If a number is given in this form:
We can do the operation below to make it improper fraction:
The bigger number is . So we subtract the other from this after changing to improper fraction.
and
Now, we subtract via doing LCM and get our answer:
The difference in weights = pounds
The answer will be 1 and n which make the sum equal n+1. Hope it help!
Answer:
C=89.2
Step-by-step explanation:
The formula of the circumference of a circle is C=2piR (or C=piD). Now, when calculating, plug in the numbers, giving you C=2pi14.2. Multiply everything, you get a super long irrational number; just round. You will get 89.2.
It is 230,000 because the first 9 gets rounded up because the next number is above 5
