Answer: x = -7 or x = -4
Step-by-step explanation: When an equation has a squared term in it
such as x² + 11x + 28 = 0, it's called a polynomial equation.
The rule for solving a polynomial equation
is to first set it equal to zero, then factor.
Since this equation is already set equal to zero,
our first step is to factor the left side of the equation.
To factor x² + 11x + 28, we need the factors
of 28 that add to 11 which are 7 and 4.
So we have (x + 7)(x + 4) = 0.
Whenever two terms are multiplied together to equal zero,
this means that either one or the other must equal zero.
So if (x + 7)(x + 4) = 0, then either x + 7 = 0 or x + 4 = 0.
Solving each equation from here, we get x = -7 or x = -4.
So our solution is {-7, -4}.
Hi
The answer is 2.6
I'm sorry if it's incorrect
The equilibrium price in a market is the price where the quantity demanded of the products are equal
The equilibrium price in the market is $2
<h3>How to determine the
equilibrium price </h3>
From the given supply and demand data for wheat:
When the price is $2, the quantity demanded and the quantity supplied for wheat is 61
This means that the equilibrium price $2
Hence, the equilibrium price in the market is $2
