Answer:
The answer is D
Step-by-step explanation:
To be a function, you cannot have the same x values.
this is hard but I don't understand your language
The least common multiple of 9, 3, and 18 is 18.
Convert 1/9 to 2/18.
Convert 2/3 to 12/18.
Then add the numerators:
2 + 12 + 5 = 19
So the answer is 19/18, or 1 1/18 if you prefer.
⇒ s = a+b+c2=5+12+132 a + b + c 2 = 5 + 12 + 13 2 = 15 cm.
Area of the base = √s(s−a)(s−b)(s−c)
= √15×10×3×2 15 × 10 × 3 × 2 cm2 = 30 cm2
