Although part of your question is missing, you might be referring to this full question: The two square pyramids are similar. The side length of the smaller pyramid is 3/4 the side length of the larger pyramid. Which fraction represents the ratio of the base area of the smaller pyramid to the base area of the larger pyramid?
The answer to the given question is 9/16. The fraction represents the ratio of the base area of the smaller pyramid to the base area of the larger pyramid is 9/16.
<h3>What is Area in Mathematics?</h3>Area is defined as the total space taken up by a flat (2-D) surface or shape of an object. We measure area in square units (cm² or m²). Area is calculated by multiplying the length of a shape by its width.
The ratio of areas of 2 similar squares is the square of the ratios of their similar side lengths. Since the ratio of the smaller side length to the larger side length is 3/4, then the ratio of areas of two similar squares is:
(3/4) ² = 3²/4² = 9/16.

Answer:
<em>Numbers: 6 and -2</em>
Step-by-step explanation:
<u>Equations</u>
This question can be solved by inspection. It's just a matter of factoring 12 into two factors that sum 4. Both numbers must be of different signs and they are 6 and -2. Their sum is indeed 6-2=4 and their product is 6*(-2)=-12.
However, we'll solve it by the use of equations. Let's call x and y to the numbers. They must comply:
Solving [1] for y:
Substituting in [2]
Operating:
Rearranging:
Solving with the quadratic formula:
With a=1, b=-4, c=-12:
The solutions are:
This confirms the preliminary results.
Numbers: 6 and -2
