Answer:
3x^{4} + 4x³ + 5x - 6
Step-by-step explanation:
Given in the question is an expression
(3x³ - 2x² + 4x - 3)(x + 2)
Apply distributive law
(3x³ - 2x² + 4x - 3)(x) + (2)(3x³ - 2x² + 4x - 3)
3 - 2x³ + 4x² -3x + 6x³ - 4x² + 8x - 6
Rearrange the like terms
3 + x³(-2+6) +x²(4-4) +x(-3+8) - 6
3 + 4x³ + 5x - 6
After performing indicated operation the result is

Answer:
C: (-8,3) R:5
Step-by-step explanation:
The equation of a circle can be written as:
(x-h)^2+(y-k)^2=r^2
where (h,k) is the center, and r is the radius
We have the equation:
(x+8)^2+(y-3)^2=25
Center:
The center is (-8,3)
(x+8)^2--> (x-h)^2
Therefore the x coordinate of the center is -8
(y-3)^2-->(y-k)^2
Therefore the y coordinate of the center is 3
Radius
r^2=25
Take the square root of both sides
r=5
