while excluding 0, the product and quotient is positive if operating between same sign, otherwise if we operating different sign will resulted negative.
Answer:
hello :
Step-by-step explanation:
f(x) = 2x²+5√(x-2)
f(x) exist : x - 2 ≥ 0 : x ≥ 2
The domain for f(x) is all real numbers "greater" than or equal to 2

Answer:
x = 3.51
Step-by-step explanation:
Since, formula to determine the area f a triangle is,
Area = 
8 = 
16 = x(3x - 7) + 1(3x - 7)
16 = 3x² - 7x + 3x - 7
16 = 3x² - 4x - 7
0 = 3x² - 4x - 23
3x²- 4x - 23 = 0
By quadratic formula,
x = 
x = 
x = 
x = 
x = 3.51, -2.18
But the length of sides can't be negative.
Therefore, x = 3.51 will be the answer.
