I=$720, P=$1000, r=9%

UNO [17]

I = PRT

720 = (1,000)(0.09)(t)
720 = 90(t)
720/90 = t
8 = t or t = 8

I am not sure if it is terms of months or years but 8 is the answer. hope it helps :)

Find the number that we can place in the box, so that the resulting quadratic is the square of a binomial.

Arturiano [62]

We need a number to complete

$(x+c)^2=x^2+2xc+c^2$

Since we have

$2xc=\dfrac{4}{5}x \iff 2c=\dfrac{4}{5}\iff c=\dfrac{4}{10}=\dfrac{2}{5}$

And so the expanded square is

$\left( x+\dfrac{2}{5}\right)^2=x^2+\dfrac{4}{5}x+\dfrac{4}{25}$

Answer:

First Picture:

$\sqrt{x} -3=3-\sqrt{x}\\\\\x-3=0\\ +3 +3\\x=3$

Second Picture:

$2/3(9x-6)-4=9x-6$

$(6x-4-4=9x-6\\6x-8=9x-6\\ -9 -9\\\\-3x-8=-6\\ \\+8 +8\\-3x=2\\\\x=-2/3$
