I gave the answer in the picture
Answer:
5x^4+ 2x^3+3x² – 3x + 2
Step-by-step explanation:
(5x^4+ 2x^3– 1)+(3x² – 3x + 3)
Combine like terms
5x^4+ 2x^3+3x² – 3x + 3– 1
The only like terms are the constants
5x^4+ 2x^3+3x² – 3x + 2
I think the circle would grow bigger into an oval.
Answer:
1 minute
Step-by-step explanation:
We can see that Lisa types 165 words in 3 mins.
So she types 55 words in 1 minute.
How did I work that out?
Well, all you really do is 
which is equal to 
if you divide top and bottom by 3. Anything divided by 1 is itself.
To make this easy let covert everything using a LCD.
The LCD of 1/4 1/12 and 1/6 is 12. This becomes...
Tom ate 3/12 of the pizza.
Leftover pizza = 9/12.
Slices were 1/12.
X friends got pizza.
Remaining pizza is 2/12.
if each friend got 1 piece(1/12)....
9/12(Leftovers) - 2/12(remaining) = 7/12
So 7 friends got pizza.
