Given a polynomial p(x) with leading coefficient 
and solutions 
, we have
That's why we have to find the solutions first. We complete the square by adding 3 to both sides:
From here, we continue by taking the square root of both sides:
So, the two solutions are
Which yields the factorization
Answer:
9
Step-by-step explanation:
just do 16 - 5 its exactly the same
$80 but give the other person Brainliest :D
Answer:
I think answer is B Altitude
Refer to the diagram shown below.
The height of the pole is CD (3 m), and its shadow is AB (1.22 m).
The height of the building is h m, and its shadow is AD (38.5 m).
The two triangles ΔABC and ΔADE are similar because of AAA.
Therefore
Cross multiply.
1.22 h = 3*38.5 = 115.5
h = 115.5/1.22 = 140.91 m
Answer: 141 m (nearest meter)
