A person invests 3500 dollars in a bank. The bank pays 5% interest compounded semi-annually. To the nearest tenth of a year, how long must the person leave the money in the bank until it reaches 8900 dollars? A=P(1+\frac{r}{n})^{nt}

y = x + 95

y = 42 + 95

y=137 mm hg

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.
