Answer:
negative 9 plus or minus the square root of 17 divided by 8
Step-by-step explanation:
move all terms to one side
4x^2 + 9x + 4= 0
Use the quadratic formula
and you get negative 9 plus or minus the square root of 17 divided by 8
You calculate
<span>[-10 +(-3)]-[6+(-9)]</span>
=[-10-3]-[6-9]
=-13-[-3]
=-13+3
= -10
We know that, In a Right Angled Triangle :
✿ (Hypotenuse)² = (First Leg)² + (Second Leg)²
From the Diagram :
✿ Hypotenuse = x
✿ First Leg 
✿ Second Leg 
Given:
The equation of circle is
To find:
The polar form of given circle.
Solution:
We have,
![[\because (a+b)^2=a^2+2ab+b^2]](https://tex.z-dn.net/?f=%5B%5Cbecause%20%28a%2Bb%29%5E2%3Da%5E2%2B2ab%2Bb%5E2%5D)
Subtracting 9 from both sides, we get
We know that, 
and 
.
and 
We know that, r is radius it cannot be 0. So,
Therefore, the correct option is A.
If my memory does not remember wrong you have to multiply 1.63x1.84=2.9992 after this you have y=2.9992x, you have to substituted the x for 5 y=2.9992(5) and that will equal to y=14.996 and rounded will be 15 hope I was able to help
