Answer:
1). (x² + 5) and (x + 4)
2). (x²- 3) and (x + 11)
Step-by-step explanation:
We have to determine the factors of the given expression (x³ + 4x² + 5x + 20) by grouping method.
x³ + 4x² + 5x + 20
= x²(x + 4) + 5(x + 4)
= (x² + 5)(x + 4)
Therefore, factors of the given expression are (x² + 5) and (x + 4).
Second expression is (x³ + 11x² - 3x - 33)
Now we will find the factors of this expression by grouping.
x³ + 11x² - 3x - 33
= x²(x + 11) - 3(x + 11)
= (x² - 3)(x + 11)
Therefore, the factors of the given expression are (x² - 3) and (x + 11).

Answer:
79.2 g of sugar is needed.
Step-by-step explanation:
9.9 times 8 is 79.2.
You can prove this by dividing 79.2 by 8 and you will get 9.9 as the answer.
Answer:
See answer below
Step-by-step explanation:
Hi there,
Get started by developing a relationship between the amount of sugar for 1 cake. We can use dimensional analysis to solve this.
Now, we know that we need 8 cakes. We put 1 cake on the bottom of the fraction so that it cancels out with the 8 cakes unit:
thanks,
Given data:
Sample size
Sample proportion of people support candidate A:
Population proportion of people support Candidate A :
Check the condition: and
Null Hyposthesis:
Alternative Hypothesis:
The test statistics:
Plug in p=0.56, P=0.40 and n=100 in the above formula,
The table value of z at 10% of significance level is 1.28
Table value is less than the calculated value.
Hence is rejected at 10% level.
Therefore there is the evidence at an alpha level of 10% to conclude that the percentage of people who support candidate A has changed.
