1 answer:
jonny [76]3 years ago
6 0

Answer:

Step-by-step explanation:

1) x² - 8x + 5 = 0

2) No subtract 5 from both sides

x² - 8x + 5 - 5 = 0 - 5

x² - 8x  = -5

3) Now find (8/2) = 4. Add 4² = 16 to both sides

x² - 8x + 16 = -5 + 16

x² - 8x + 16 = 11

4) (x - 4)²  = 11

5) Take square root both sides

x - 4 = ±√11

x = 4 ±√11

Jeff has five less than twice the number of clients that Kenan has. The product of the number of clients they have is 322. Write
HACTEHA [7]

Answer:

The equation that represents this situation is 2c² - 5c - 322 = 0

Step-by-step explanation:

∵ Kenan has c clients

∵ Jeff has five less than twice the number of clients that

   Kenan has

- That means multiply c by 2 and then subtract 5 from the

   product to find the number of Jeff's clients

∴ Jeff's clients = 2c - 5

∵ The product of the number of clients they have is 322

∴ c × (2c - 5) = 322

- Multiply c by the bracket (2c - 5)

∴ (c)(2c) + (c)(-5) = 322

∴ 2c² + (-5c) = 322

- Remember (+)(-) = (-)

∴ 2c² - 5c = 322

- Subtract 322 from both sides

∴ 2c² - 5c - 322 = 0

The equation that represents this situation is 2c² - 5c - 322 = 0

Find m &lt; b<br><br>Picture Included
lana66690 [7]

Answer:

<b= 48 degree

Step-by-step explanation:

<A + <B + <C = 180 degree (Sum of angles in a triangle)

<A = 90 degree

<B = 2x + 14 degree

<C = 4x - 26 degree

90+2x+14+4x-26=180 degree\\2x+4x=180+26-90-14\\6x=102\\x=\frac{102}{6} \\x=17 degree\\

Therefore, <B = 2x + 14 = 2(17) + 14 = 34 + 14 = 48

<b = 48 degree
