On a chapter test, stephanie uses the rules of equation solving and inverse operations to solve the cubic equation below. the directions on the test are not very specific; however, they do say to give an exact solution. stephanie is not sure if she should submit a decimal approximation or a simplified radical as the answer. 4x^3 = 756

1. what recommendation can you make to stephanie regarding her answer to the cubic equation above? in your recommendation, explain what the term "exact" indicates with regards to the solution.
2. solve the cubic equation from stephanie’s test. submit two solutions for the equation- a) your answer as a decimal approximation, rounded to the nearest hundredth, and b) as a simplified radical. use substitution to check each version of your solution in the original equation.
3. after solving the test question and checking both the decimal solution and the simplified radical form, would you change your recommendation (in part 1) to stephanie regarding the format of her answer? use complete sentences to explain your reasoning.

15

step-by-step explanation:

we are given the following expression and we are to solve it and find the product:

-13 × (-5)

solving the given expression in the standard order of solving a mathematical expression, beginning with the opening of brackets and then multiplying the terms and changing their signs.

-3 × -5 = 15 (answer is positive because when negative is multiplied with negative, it gives a positive answer)

you have to put the graph on here with the question

step-by-step explanation:

well if he bought them at 5 cedis each sold them at 7 cedis each then he would make a profit of 2 cedis of each book. if in total he made 150 cedis profit that means he sold 75 books. he lost 12 books at the start so that means he originally bought a total of 82 books.

step-by-step explanation:

answer: - (a)

(b) 88 seats

step-by-step explanation:

given: in an auditorium, there are 22 seats in the first row and 28 seats in the second row.

thus first term=

second term=

the number of seats in a row continues to increase by 6 with each additional row.

⇒d= 6

a) given formula :

b)   let the number of seats (n) = 12

substitute n=12 in the explicit rule formed in (a)

∴there are 88 seats in 12 rows.
