Answer:

answer is no, not a right triangle

Step-by-step explanation:

if it is a right triangle then the sum of the square of the two smaller legs will equal the square of the longest leg

does 8² + 12² equal 15²?

64 + 144 = 225

208 ≠ 225

answer is no, not a right triangle

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
