The product of the algebraic expressions and is . Hence, <u>3rd option</u> is the right choice.
<h3>How do we multiply two algebraic expressions?</h3>
When two algebraic expressions are multiplied, the like terms are to be combined and multiplied, and then they should be written as a single algebraic expression.
<h3>How do we solve the given question?</h3>
In the question, we are asked to find the product of the algebraic expressions and , that is:
()().
To find the product of the two expressions, we combine the like terms:
= (Using the law of exponents: )
Now we write them as a single expression: .
∴ The product of the algebraic expressions and is . Hence, <u>3rd option</u> is the right choice.

Answer:
D) 16 square units
Step-by-step explanation:
The base can be considered to be the line x=-3. The extent of the triangle along that line is from y=-4 to y=4, so is 8 units.
The "height" of the triangle can be considered to be the distance from the vertex at x=-7 to the line at x=-3, so is 4 units.
The area of the triangle is half the product of these measures:
A = (1/2)bh = (1/2)(8 units)(4 units) = 16 square units
