Answer:
Explain why you chose this method. Summary: The factoring method can be chosen to solve the equation 2x2 - 7 = 9. It is one of the easiest methods as we can isolate the variable by factoring out the GCF and obtain the values.

Answer:
O Interview with Hispanic teenage girl.
Explanation:
A primary source is a source that is used to support an argument or claim made. And that source is primary because of its source, meaning, it is not rewritten or reproduced, or revised. It contains the first-hand account or an account told by a person who is a witness to that particular event.
A quinceañera is a coming-of-age event popular among the Hispanic community when a girl turns 15 years old. This celebration is a sort of welcome party for a girl from girlhood to womanhood. This practice is done to mark the change in the girl and a welcome into the world of adulthood.
An interview with a Hispanic teenage girl will be the best primary source for a quinceañera because she would have already gone through the event herself and would present the best first-hand account of the celebration.
Thus, the correct answer is the fourth/last option.
Answer:
D) the process of building versions of a product until the design is perfect
Explanation:
A product can be defined as any physical object or material that typically satisfy and meets the demands, needs or wants of customers. Some examples of a product are mobile phones, television, microphone, microwave oven, bread, pencil, freezer, beverages, soft drinks etc.
For example, a product such as a software application undergoes several developmental stages before it becomes a single unit.
Software development life cycle (SDLC) can be defined as a strategic process or methodology that defines the key steps or stages for creating and implementing high quality software applications.
Some of the models used in the software development life cycle (SDLC) are;
I. A waterfall model: it can be defined as a process which involves sequentially breaking the software development into linear phases. Thus, the development phase takes a downward flow like a waterfall and as such each phase must be completed before starting another without any overlap in the process.
II. An incremental model: it refers to the process in which the requirements or criteria of the software development is divided into many standalone modules until the program is completed.
III. A spiral model: it can be defined as an evolutionary SDLC that is risk-driven in nature and typically comprises of both an iterative and a waterfall model. Spiral model of SDLC consist of these phases; planning, risk analysis, engineering and evaluation.
Hence, an iterative design refers to the process of building versions of a product until the design is perfect.
It's possible that the answer is weight
