Thanks :)
Bad choice of word I would have just preferred to factorise rather than use the formula.
. . . I'm a bit ashamed I didn't see those factors
The length of a room is 1 more than 3 times its width. The area of the room is 80 square meters. Find the demensions.
$$w\times{l}=A$$
$$w\times({3w+1})=80$$
$$3w^2+w=80$$
$$3w^2+w-80=0$$
$$w=\frac{-1+\sqrt{1^2-4\times{3}\times{-80}}}{2\times{3}}$$ or $$w=\frac{-1-\sqrt{1^2-4\times{3}\times{-80}}}{2\times{3}}$$
$$w=\frac{-1+\sqrt{961}}{6}$$ or $$w=\frac{-1-\sqrt{961}}{6}$$
$$w=\frac{{-1}+31}{6}$$
$$\mathbf{w=5}$$
$$l=3\times{5}+1}$$
$$\mathbf{l=16}$$
Fixed!
$${\mathtt{44.7}} = {\frac{{\mathtt{100}}}{{\mathtt{x}}}}$$
$${\mathtt{44.7}}{\mathtt{\,\times\,}}{\mathtt{x}} = {\mathtt{100}}$$
$${\mathtt{x}} = {\frac{{\mathtt{100}}}{{\mathtt{44.7}}}} = {\frac{{\mathtt{1\,000}}}{{\mathtt{447}}}}$$
Amount = Principle*(1 + rate)^Times compunded
A=P(1+r)^n
For 5 years:
A = 4500*(1+0.065)^5
A = $6165.39
For 12 years:
A = 4500*(1+0.065)^12
A = $9580.93
Nice
I didn't think of doing it like that. The more direct route for sure.
Am I driving the bus . . .? It's mine after all.
