Find the area of each parallelogram a equals base height 11 in 9 in​
Paul [167]

Answer:

Area of the parallelogram is 99 inch²

Step-by-step explanation:

We are given that,

Base of the parallelogram = 11 inches

Height of the parallelogram = 9 inches

Since, we know,

Area of a parallelogram = Base × Height

So, we get,

Area of the parallelogram = 11 × 9 = 99 inch²

Hence, the area of the parallelogram is 99 inch².

The solution to the system of equations is (-1, 1) and (1, -1)

<h3>How to determine the solution to the system of equations?</h3>

The system of equations is given as:

x^3 + x^2y + xy^2 + y^3 = 0

x^2 + 4y^2 = 5

The equations in the above system of equations are nonlinear equations.

The best way to a system of equations that are nonlinear equations is by the use of graphs

So, we start by plotting the graphs of the equations in the system of equations given as x^3 + x^2y + xy^2 + y^3 = 0 and x^2 + 4y^2 = 5

See attachment for the graph

The point of intersection represents the solution

From the attached graph, the points of intersection of the equations are

(-1, 1) and (1, -1)

Hence, the solution to the system of equations is (-1, 1) and (1, -1)
