Question

Use either the square of a binomial or difference of squares to find the area of the square.

hintHint:

The methods used to find the product of binomials are called special products.
Multiplying a number by itself is often called squaring.
For example (x + 3)(x + 3) = (x + 3)2
Area of square = (side)2

The correct answer is: 2916


    Area of the given square is 542
    542 can be written as 54  54 which can be further written as (50 + 4)(50 + 4)
    (50 + 4)(50 + 4) = 50(50 + 4) + 4(50 + 4)

    = 50(50) +  50(4) + 4(50) + 4(4)

    = 2500 + 200 + 200 + 16

    = 2500 + 400 + 16

    = 2916 cm2
    Final Answer:
    Hence, the Area of the square of side 54 cm is 2916 cm2

    Graph the equation straight Y equals negative 0.5 straight x

    We can find the tabular values for any points of x and then plot them on the graph. But we usually choose values for which calculating y is easier. This makes plotting the graph simpler. We can also find the values by putting different values of y in the equation to get different values for x. Either way, we need points satisfying the equation to plot its graph.
