Answer:

What Wally did wrong is that it is supposed to be (4a-5)(a-4)

In order to get -21 a. He was supposed to use negative 5 and 4 to get to negative 21

If he used (4a+5)(a+5)

The answer will be positive 21 and that's not what the problem is asking

Step-by-step explanation:

Hope this helps :)

draw a basic market graph. Title it the market for the product in your news article. Label axes, curves, eqilibruim price and eq
Vaselesa [24]

The basic market graph is attached below.

<h3>What do you mean by market equilibrium?</h3>

A market is said to have reached equilibrium price when the supply of goods matches demand.

The equilibrium price is the only price where the plans of consumers and the plans of producers agree, where the amount consumers want to buy of the product, quantity demanded, is equal to the amount producers want to sell, quantity supplied. This common quantity is called the equilibrium quantity.

Quantity of gasoline:

Explanation of graph: The demand curve, D, and the supply curve, S, intersect at the equilibrium point E, with an equilibrium price of 1.4 dollars and an equilibrium quantity of 600.

The equilibrium is the only price where quantity demanded is equal to quantity supplied. At a price above equilibrium, like 1.8 dollars, quantity supplied exceeds the quantity demanded, so there is excess supply.

At a price below equilibrium, such as 1.2 dollars, quantity demanded exceeds quantity supplied, so there is excess demand.

Please help I do not understand

Answer:

The coefficients are;

1,28,378 and 3,276

Step-by-step explanation:

For the binomial expansion, when we talk of the coefficients, we mean the whole numbers that stands before the alphabets

For example, the coefficient of x in 2x is 2

Back to the question;

(x + y)^28

= 28C0 x^28y^0 + 28C1 X^27y^1 + 28C2 x^26y^2 + 28C3 x^25y^3 + ..........

So the coefficients we are looking for are;

28C0 = 1

28C1 = 28

28C2 = 378

28C3 = 3,276

Kindly note that 28C0 is read as 28 combination zero and so on
