Answer:
B, E, and F.
Step-by-step explanation:
We can apply synthetic division when dividing a polynomial P(x) by a binomial in the form (x - a).
Looking at the coefficients, we can see that our dividend is:
Our divisor will be (x - a), where a is the number on the very top left.
So, a = 2.
Thus, our divisor is:
Note that our remainder is 0.
So, the synthetic division shown is telling us that:
Hence, E is the correct choice. A uses the incorrect divisor.
If the divisor successfully divides with no remainder, then the divisor is a factor.
Since (x - 2) successfully divided with no remainder, (x - 2) is indeed a factor of the polynomial.
Hence, B is also correct.
C uses the wrong factor.
D uses the wrong value. It should be positive 2.
So, F is the correct choice.
Therefore, the answers are: B, E, and F.
Answer:
You will need to buy 5 1.50lb bags of sugar to make your recipe.
Step-by-step explanation:
This problem can be solved by consecutive rules of three.
A large recipe calls for 3.18kg of sugar. Your bags of sugar are measured in pounds (lb). Remembering that 1kg=2.20462lb
How many lbs of sugar you will need to buy?
1 kg - 2.20462lb
3.18 kg - x lb
How many 1.50lb bags of sugar will you need to buy to make your recipe?
1 bag - 1.50 lb
x bags - 7 lb
You will need to buy 5 1.50lb bags of sugar to make your recipe.
