Factor (3x+2)(3x^2-6x+4)
Answers
Answer:
(3x+2)(3x-2)(x-2)
Step-by-step explanation:
1. you do trinomial factoring for the second factor (the one with three terms)
2. you put a 3x in one parentheses and an x in the other and find all the numbers that make positive 4.
3. Now foil (first,outside,inside,last) and see which ones match the factor above
4. You should be left with three factors at the end.

To write a fraction as a percent, first remember that a percent is a ratio of a number to 100. If we want to write as a percent, we need to find a fraction equivalent to
that has a 100 in the denominator. We can do this by setting up a proportion.

Now, we can use cross products to find the missing value.

N = 12
Therefore, is equal to
or 12%.
Answer : 12%
Anything over 100 is a percent. 1/100 = 1% 2/100 = 2% etc . . .

According to the model, how many more pizzas are sold for each additional coupon issued?
1 pizzas
3.4 pizzas
4.3 pizzas
43 pizzas
46 pizza
Answers
Answer:
B. 3.4 pizzas.
Step-by-step explanation:
We have been given a scatter plot, which represents the number of pizzas (y) sold during weeks when different numbers of coupons (x) were issued. The equation represents the linear model for this data:
We can see that our given equation is in form of slope intercept form: , where m= slope of line and b = y-intercept.
We can see from our given equation that y-intercept is 43, when no coupons were issued, there were 43 pizzas sold. 43 is constant and it will not change by any change in x.
The slope of our line is 3.4, which represents change in number of pizzas with respect to change in number of coupons issued. Therefore, 3.4 more pizzas are sold for additional coupon issued and option B is the correct choice.
