Answer:
6x^3 + 29x^2 + 26x -21
Step-by-step explanation:
(2x^2 + 5x -3)(3x + 7) = 6x^3 + 14x^2 + 15x^2 + 35x - 9x -21
= 6x^3 + 29x^2 + 26x -21
18.56 feet
Catie creates a similar triangle with the ladder so we can create a proportion to solve for the height.

Convert all values to feet . 16in = 1.33 ft . 5ft 6 in = 5.5 ft
Insert values into proportions

Cross multiply to get
24.75=1.33x
divide both sides by 1.33
x=18.56ft
$326.83 goes towards the principal after your first payment.
Answer: (141.1, 156.48)
Step-by-step explanation:
Given sample statistics : 


a) We know that the best point estimate of the population mean is the sample mean.
Therefore, the best point estimate of the mean weight of all women = 
b) The confidence interval for the population mean is given by :-
, where E is the margin of error.
Formula for Margin of error :-

Given : Significance level : 
Critical value : 
Margin of error : 
Now, the 90% confidence interval for the population mean will be :-

Hence, the 90% confidence interval estimate of the mean weight of all women= (141.1, 156.48)
only integers and polynomials are under subtraction.
