1) Volume = area * height => height = volume / area
2)
x^4 + 4x^3 + 3x^2 + 8x + 4
height = --------------------------------------
x^3 + 3x^2 + 8
That division is not exact
The result of this division is x + 1 plus a residue of - 8x^2 + 8x - 4.
It was expected an exact division, so likely some of the terms is not properly written. Now you know the procedure and can perform it with the right terms.
Answer:
x=-12
Step-by-step explanation:
because 8-12 geta you -4
Q.13 is no solution since the y intercept of the 2 equation differ but gradient is the same therefore if you were to draw a graph there wont be any intersection between the equations
the next question's answer is no solution
Answer:
x = -10
Step-by-step explanation:
expand
simplify 36 - 4.5x + 36 to -4.5x + 72
simplify 102 - 7.5x - 60 to -7.5x + 42
add 7.5x to both sides
simplify -4.5x + 72 + 7.5x to 3x + 72
subtract 72 from both sides
simplify 42 - 72 to -30
divide both sides by 3
simplify 30/3 to 10
Answer: x = -10
