2(x^2 - 2x + 1) + 3
= 2x^2 - 4x + 2 + 3
= 2x^2 - 4x + 5
Answer:
-2
Step-by-step explanation:
1 and 2/3 can also be written as 5/3, therefore you need to do -1/3 - 5/3 which gives you -6/3 which is -2.
Answer:
half of 5 is 2.5
2.5 x 3.14 x 2 = 15.7 cm
Formula of circumference:
2(you just always need this number when finding circumference) x pi(3.14 or 22/7 depending on what they tell you to use) x r(radius, half of your diameter or given radius).
I know it's a very small number, but I don't have access to a calculator for the exact answer :)
It's a small number + about 1/9
Final answer:
it rounds to about 1/9
Assuming the special right triangle properties are right lol
