Answer: 2x³ - 3x² + 7x + 8</h2>
Step-by-step explanation:
Sum = 4x³ - 3x² + 3x + 8 + (6x³ - 7x² + 4x) + (-8x³ + 7x²) <em>[write the terms as given by the quetion and group like terms]</em>
<em />
⇒ Sum = (4x³ + 6x³ - 8x³) + (- 3x² - 7x² + 7x²) + ( 3x + 4x) + 8 <em> [complete the addition of like terms]</em>
<em />
∴ sum = 2x³ - 3x² + 7x + 8
The present age of Ahmed and Ahmed's father is 12 and 36 respectively.
Step-by-step explanation:
Given : Ahmed's father is thrice as old as Ahmed. After 12 years, his age will be twice that of his son.
To Find : Their present age ?
Solution :
Let the Ahmed's age be 'x'.
Ahmed's father is thrice as old as Ahmed.
i.e. Ahmed's father age is '3x'
After 12 years, his age will be twice that of his son.
i.e. 3x+12 = 2(x+12)3x+12=2(x+12)
Solving the equation,
3x+12 = 2x+243x+12=2x+24
x=12x=12
So, Ahmed's age is 12.
Ahmed's father age is 3\times 12=363×12=36
Therefore, The present age of Ahmed and Ahmed's father is 12 and 36 respectively.

Consider the given equation to be f(x) whose first derivative is positive for all real x. This implies f(x) is a strictly increasing function. Thus it has only 1 root.
Answer:
Costs are $490
49 shirts are sold
98 + 8x = 10x
98 = 2x
49 = x
98 + 8(49) = $490 in costs

Step-by-step explanation:
98 + 8x = 10x
98 = 2x
49 = x
98 + 8(49) = $490 in costs
