Answer:

Salt

Step-by-step explanation:

At its peak, Ghana was chiefly bartering gold, ivory, and slaves for salt from Arabs and horses, cloth, swords, and books from North Africans and Europeans. As salt was worth its weight in gold, and gold was so abundant in the kingdom, Ghana achieved much of its wealth through trade with the Arabs.

Hope this helps!

Answer:

2{x}^{ \frac{3}{2} }

Step-by-step explanation:

We want to simplify:

\frac{ {x}^{2} +  {x}^{2}  }{ {x}^{ \frac{1}{2} } }

We first simplify the numerator to obtain:

\frac{ 2{x}^{2}  }{ {x}^{ \frac{1}{2} } }

Next the quotient rule:

\frac{ {a}^{m} }{ {a}^{n} }  =  {a}^{m - n}

We apply this quotient rule to get:

\frac{ 2{x}^{2}  }{ {x}^{ \frac{1}{2} } }  = 2{x}^{2 -  \frac{1}{2} }

Simplify exponents:

\frac{ 2{x}^{2}  }{ {x}^{ \frac{1}{2} } }  = 2{x}^{ \frac{3}{2} }

Therefore the given expresion simplifies to:

2{x}^{ \frac{3}{2} }

For the function , f(x) = 2x + 1. If f(x) = 3 , what is the value of x?
kodGreya [7K]

Answer:

For functions, the two notations mean the exact same thing, but "f (x)" gives you more flexibility and more information. You used to say "y = 2x + 3; solve for y when x = –1". Now you say "f (x) = 2x + 3; find f (–1)" (pronounced as "f-of-x equals 2x plus three; find f-of-negative-one").
