If p(x) = 2x2 – 4x and q(x) = x – 3, what is mc007-1.jpg? 2x2 – 4x + 12 2x2 – 16x + 18 2x2 – 16x + 30 2x2 – 16x + 15
Rainbow [258]
P(x) = 2x² - 4xq(x) = x - 3
To find the answer, we plug q(x) into p(x):
p(q(x)) = 2(x - 3)² - 4(x - 3)p(q(x)) = 2(x² - 6x + 9) - 4x + 12p(q(x)) = 2x² - 12x + 18 - 4x + 12p(q(x)) = 2x² - 16x + 30
The third option is correct.

19. A teacher tells 36 students to form 4 equal groups. Write and solve a
olchik [2.2K]

4 x = 36

Step-by-step explanation:

Because the groups have an equal number of students, we assume that each of the groups has <em>x </em>number of students.

Therefore since there is <em>x</em> number of students in each of the 4 groups, there is 4 * x number of total students in all groups combined.

Since the question already indicates that there are a total of 36 students in the class, then we can indicate that..

4x = 36
