Answer:

The dimensions are:

3(2x+1) by (7x+5)

Step-by-step explanation:

The area of the rectangle is given as

A=42x^2+51x+15

The factored form of this quadratic trinomial gives the dimensions of the rectangle.

We factor 3 first to obtain;

A=3(14x^2+17x+5)

We split the middle term to get;

A=3(14x^2+10x+7x+5)

We factor within the parenthesis to get;

A=3(2x(7x+5)+1(7x+5))

We factor further to get;

A=3(2x+1)(7x+5)

The dimensions are:

3(2x+1) by (7x+5)

Then the perimeter will be

2(6x+3+7x+5)=26x+16\:\:\:\boxed{\sqrt{} }

You buy school clothes during a sale when everything in the store is 15% off. Which of the following could describe
Savatey [412]

Answer:

(29.99 + 18.65 + 32.59) 0.85 = 0

(29.99 + 18.65 + 32.59) - 0.15(29.99 + 18.65 + 32.59) = 0

Step-by-step explanation:

The 15% off represents percentage discount. The relationship between percentage discount and total cost is given by the equation;

Actual cost - (Percentage discount) Actual cost = Total cost

The correct options are;

(29.99 + 18.65 + 32.59) 0.85 = 0

(29.99 + 18.65 + 32.59) - 0.15(29.99 + 18.65 + 32.59) = 0

A dependent variable is the variable being tested, measured or predicted in an experiment. I.e a outcome

In this case, the the effects of the amount tutors are paid a week before exam, the amount of sleep before exam and the number of study hours are input variables to determine or predict a students score in exam

The independent variables are;

x1 =represents the amount paid to a tutor (in dollars) in the week before the exam

x2 = represents the number of hours of sleep in the week before the exam

x3 = number of study hours in the week before the exam

The dependent variable is the exam score

B0, B1, B2,B3, B4 are coefficients
