Solve x for (x-2)²-6x=1

Mathematics
1 answer:
Roman55 [17]3 years ago
4 0

Answer:

x ≈ 9.69, 0.31

Step-by-step explanation:

Given:

(x - 2)² - 6x = 1

We'll expand the squared binomial on the left:

x² - 4x + 4 - 6x = 1

Group like terms:

x² - 10x + 4 = 1

Complete the square by adding 21 to both sides:

x² - 10x + 25 = 22

(x - 5)² = 22

And solve for x:

x - 5 = √22

x = 5 ± √22

x ≈ 9.69, 0.31

An art teacher has 28 students in her first-period class and 24 students in her second-period class. If almost 30% of the studen
Goshia [24]
Answer:
C. 8


Explanation:
One way to solve this is to find 30% of each class, 28 and 24.

30% of 28:
28 • 0.30 = 8.4
30% of 24:
24 • 0.30 = 7.2

You can then find the average of these two numbers.

8.4 + 7.2 = 15.6
15.6 ➗ 2 = 7.8
7.8 rounds up to 8

Another way to solve is to first find the average number of people in each class.

28 + 24 = 52
52 ➗ 2 = 26

You can then find 30% of this number.

26 • 0.30 = 7.8
7.8 rounds up to 8
