B. X^2-6x. =14
Half of -6 is -3 and -3^2=9 so add 9 to both sides
X^2-6x+9 = 14+9
(X-3)^2= 23

Answer:

(x-3)² = 23 Option B

Step-by-step explanation:

Given quadratic is :

x² - 6x - 14 = 0

Use complete the square method

Move loose term from left side to right side.

x² - 6x = 14

add both the side square of half coefficient of x that is,

half of -6 = -3

square of -3 = 9

Add both the side 9

x² - 6x + 9 = 14 + 9

(x - 3)² = 23

this is same as (x-3)²=23 second option

That's the final answer.

10. A bell rings every 25 minutes while another bell rings every 40 minutes. If the bells rang together at 6 A.M., at what time

Ivahew [28]

Answer:

9:20 A.M.

Step-by-step explanation:

Let's list out the points at which the 25-minute bell rings:

25 mins, 50 mins, 1 hour 15 mins, 1 hour 40 mins, 2 hours 5 mins, 2 hours 30 mins, 2 hours 55 mins, 3 hours 20 mins

Next let's list out the points at which the 40-minute bell rings:

40 mins, 1 hour 20 mins, 2 hours, 2 hours 40 mins, 3 hours 20 mins

From the lists above we see a common multiple of 3 hours and 20 minutes.

So, to find what time they ring after 6 A.M. add 3 hours and 20 minutes to it.

6 AM + 3 hours and 20 minutes = 9:20 A.M.

Thus, both bells would ring together again at 9:20 A.M.

Hope this helps!!

Write and solve an equation to find the value of x and the missing angle measures.

Oksana_A [137]

Answer:

Step-by-step explanation:

1). Since, both the angles are vertically opposite angles,

Measure of both the angles will be same.

6x = 30

x = 5

2). Since, both the angles are the linear pair of angles,

(4 + 5x)° + (x + 2)° = 180°

6x + 6 = 180

6x = 180 - 6

x = $\frac{174}{6}$

x = 29

Therefore, (4 + 5x)° = 4 + 5(29)

= 149°

And (x + 2)° = (29 + 2)

= 31°

3). Since, both the angles are linear pair of angles,

5x° + (3x + 12)° = 180°

8x + 12 = 180

8x = 180 - 12

x = $\frac{168}{8}$

x = 21

Therefore, 5x° = 5(21)

= 105°

(3x + 12)° = 3(21) + 12

= 75°
