9x-8=9x-3/2 X3
9x-8=27x-9/2
2(9x-2)=27x-9
18x-4 =27x-9
18x-27x=-9+4
-9x =-5
9x=5
X=5/9 answer
Answer:
C. 54π + 20.25√3 cm²
Step-by-step explanation:
The shaded area can be split into two areas: a sector and an isosceles triangle.
Area of a sector is:
A = (θ/360°) πr²
where θ is the central angle and r is the radius.
Area of an isosceles triangle can be found with SAS formula:
A = ½ ab sin θ
where a and b are two sides of a triangle and θ is the angle between them.
In this case, r = a = b = 9 cm. The central angle of the sector is 240°, and the vertex angle of the triangle is 120°. Therefore, the total area is:
A = (240°/360°) π (9 cm)² + ½ (9 cm) (9 cm) sin 120°
A = 54π + 20.25√3 cm²
i believe your answer will be 0.04 or 4/100
OR if you need an equivalent expression, that would be 81/2187

Step-by-step explanation:
<u>Factoring</u>
We need to recall the following polynomial identity:
The given expression is:
To factor the above expression, we need to find a and b, knowing a^3 and b^3. a is the cubic root of a^3, and b is the cubic root of b^3:
![a=\sqrt[3]{x^6}=x^2](https://tex.z-dn.net/?f=a%3D%5Csqrt%5B3%5D%7Bx%5E6%7D%3Dx%5E2)
![b=\sqrt[3]{64y^3}=4y](https://tex.z-dn.net/?f=b%3D%5Csqrt%5B3%5D%7B64y%5E3%7D%3D4y)
Now we apply the identity:
![x^6– 64y^3=(x^2-4y)[(x^2)^2+(x^2)*(4y)+(4y)^2]](https://tex.z-dn.net/?f=x%5E6%E2%80%93%2064y%5E3%3D%28x%5E2-4y%29%5B%28x%5E2%29%5E2%2B%28x%5E2%29%2A%284y%29%2B%284y%29%5E2%5D)
Operating:
![x^6– 64y^3=(x^2-4y)[x^4+4x^2y+16y^2]](https://tex.z-dn.net/?f=x%5E6%E2%80%93%2064y%5E3%3D%28x%5E2-4y%29%5Bx%5E4%2B4x%5E2y%2B16y%5E2%5D)
The remaining factors cannot be factored in anymore. Thus the completely factored form is:
Answer:
The Answer is 35
As comparing to 65 and 40
the x side is smallest
its 35
