First simplify both sides:2 1/5 = 11/5 1 3/4 = 7/4Then find common denominator by multiplying denominators:4/5 = 20Times denominators by opposite denominator (do to top and bottom):7/4 = 35/20 13/5 = 44/2...

We know the perimiter is split into the proportions 3:4:5 therefore by adding 3+4+5 we can work out what fraction of 72cm each side is.Thus 3/(3+4+5) = 3/12 = 1/4 is the fraction of 72 that belongs to the...

The chosen religion is Christianity. There are two conflicting Christian approaches to environmental responsibility. Namely, the concepts of stewardship and dominion.
Stewardship is the theological b...

Cosec2A - cot2A= tanA
Left hand side=1/sin2A - cos2A/sin2A
=(1- cos2A)/sin2A
=(1-(1- 2 sin^2⁡ A)/ 2sinAcosA
=(1-1 + ( 2 sin^2⁡ A))/ 2sinAcosA
=sinA/cosA
=tanA
Therefore ...

3n+2 is less then or equaled to 14. 6n divided by N squared + 5 is less then 1. First, we are going to deal with the equation on the left. From this equation, takeaway 2 from both sides to get 3n<=12, ...
