Answer:
24 m that is the answer to the question
Answer:
-9, 2/5
Step-by-step explanation:

Answer:
x² - 5x - 36
Step-by-step explanation:
Use FOIL (First, Outside, Inside, Last) to solve. x times x is x², so that is the first term of our trinomial. The outside terms are x times 4, or 4x. The inside terms are -9 and x, so -9x. The last terms are -9 times 4, or -36. We can add the like terms of 4x and -9x to get -5x. So, your trinomial is x² - 5x - 36.
ΔADB is a right triangle at ∠D
So, AB ⇒ Hypotenuse & AD,DB ⇒ Legs
∴ 
ΔADC is a right triangle at ∠D
So, AC ⇒ Hypotenuse & AD,DC ⇒ Legs

∴ BC= BD+ DC = 16 + 9 = 25
∴ The perimeter of triangle ABC = AB + BC + CA = 20 + 25 + 15 = 60.
<u>So, The correct answer is option C. 60</u>
2, 3, 1! that’s the order
