-13x + 3 is decreasing and has a negative slope.
Answer:
Solution:
Given, cost price = $784.50
Profit = 6.5% of cost price
= 6.5/100 × $784.50
= $50.9925 [since, profit% is always on C.P.]
And selling price = cost price + profit
= $784.50 + $50.9925
= $835.4925
Hence, selling price = $835.4925
They are parallel to eachother

Answer:
Step-by-step explanation:
If the square starts as n rows of n columns, adding another row of n columns will make a rectangle with dimensions n+1 rows by n columns.
__
The total number of tiles in the rectangle is said to be ...
n(n+1) = 2256
n^2 +n +1/4 = 2256 1/4 . . . complete the square
(n +1/2)^2 = (47 1/2)^2 . . . . rewrite as squares
n = 47
diagonal for rectangle= sqrt( A^2 +b^2)
diagonal for square = sqrt(2) * Side
rectangle diagonal = sqrt (14^2+7^2) = 15.65 inches
square diagonal = sqrt(2) * 7 = 9.90 inches
9.9 *2 = 19.8
the diagonal of the rectangle is not two times the length of the square
