I think it is 30 since the one at the bottom is equal to the shape of the wall.
~~6.7
Just looking at the fifth hour you can divide 60 by five to get twelve as the inches per hour. Then divide that into 80.
Or you could go about it the complex way where you find the slope of a line like this as change in y over change... stuff like that.
Area = length x width
Area = (5x + 1)*(3x - 2)
Area = 5x*3x + 5x*-2 + 1*3x + 1*-2
Area = 15x^2 - 10x + 3x - 2
Area = 15x^2 - 7x - 2 :)
Answer:
4x(3x+1)
Step-by-step explanation:
Factor 4x from the expression
The house would have slid 910 yards in 15 days.
<h3>What is a Geometric progression?</h3>
A geometric progression is a sequence in which successive terms differ by a common ratio.
It is a sequence in which the ratio of two consecutive terms is a constant.
Analysis:
first term, a= 1
second term, ar = 2
third term, ar^2= 4
common ratio = ar/a = 2/1 = 2
Sum of the G.P where n = 15
sum of G.p = a()
= 1( - 1)/2 - 1 = 32768 - 1 = 32768 inches
converting the inches to yard, where 1 yard = 36 inches
so 32768/36 = 910 yards
In conclusion, the house would slide 910 yards in 15 days.
