Paulina is remodeling her bathroom. the tile she has chosen is shown below. there are squares and trapezoids in the tile. the side length of each square in the tile is x centimeters. the height and the length of one of the bases of each trapezoid is x centimeters. the other length is 2x centimeters. a. write a simplified equation to solve for x in terms of at, the area of the tile. if necessary, use rational coefficients instead of root symbols. type your response here:

Step-by-step explanation:

For the square tile, the area of the tile is the square of the side length.

... AT = x^2

... x = AT^(1/2)

___

For the trapezoidal tile, the area of the tile is given by the formula ...

... A = (1/2)(b1 +b2)h . . . . . . where b1, b2 are the base lengths, h is the height

Filing in the values for the trapezoidal tile, we have ...

... AT = (1/2)(x +2x)x = (3/2)x^2

... x = (2/3·AT)^(1/2)

introduction, methodology, results, discussion

step-by-step explanation:

an observational study is one which consists of actual observation to record data and then analyse the data.

there are a number of factors that should be analyzed before starting an observational study.

the main four factors are:

i) introduction:   this should be analysed to check whether the purpose of the study is correctly established and the data recorded are appropriate for the study

methodology:   the method of collecting the data, such as whether randomly selected, and whether sample size matches with the population to be studied, whether questions asked are easy to answer by common men, etc.

results: then results such as summary of data with comments should be studied thoroughly

discussion:   the last is the discussion, this can be either by management people or persons who are all interested , etc.

the correct answer is you spend $55.78 more in a brand store that buy ing in a normal store.

step-by-step explanation:

brand = spend   $ 135.85 total

store = spend $80.07 total
