Answer:
x² + 6x + 9
x² + 4x + 3
x³ + 8x² + 21x + 18
x + 2
Step-by-step explanation:
Given in the question two functions,
f(x) = x² + 5x + 6
g(x) = x + 3
1) (f+g)(x)
(x² + 5x + 6) + (x + 3)
x² + 5x + x + 6 + 3
x² + 6x + 9
2) (f-g)(x)
(x² + 5x + 6) - (x + 3)
x² + 5x - x + 6 - 3
x² + 4x + 3
3) (f.g)(x)
(x² + 5x + 6) . (x + 3)
x³ + 5x² + 6x + 3x² + 15x + 18
x³ + 8x² + 21x + 18
4) (f/g)(x)
(x² + 5x + 6) / (x + 3)
(x + 2)
-------------------
(x + 3) | (x² + 5x + 6)
x² + 3x
--------------------
2x + 6
2x + 6
-----------------
0
Answer:
x =
Step-by-step explanation:
So here we are trying to find the value of x;
Subtract 5x from both sides;
-8x + 10 = -8
Then, Subtract 10 from both sides;
-8x = -18
Divide both sides by -8;
x =
Answer:
9 and 12,
Step-by-step explanation:
Answer:
Step-by-step explanation:
Solve for the first variable in one of the equations, then substitute the result into the other equation.
Add the equations in order to solve for the first variable. Plug this value into the other equations in order to solve for the remaining variables.
--->
Given:
V = 324 cu cm
h = 9 cm
Since the formula for the volume of a cylinder is V = AreaBase*height
AreaBase = V/height = 324cu cm/ 9 cm
AreaBase = 113.04 square centimetres
Therefore, the area of the pillar in square centimeters is 113.04.
