Answer:

$t \leq 18.67\ years$

Step-by-step explanation:

we know that

The simple interest formula is equal to

$A=P(1+rt)$

where

A is the Final Investment Value

P is the Principal amount of money to be invested

r is the rate of interest

t is Number of Time Periods

in this problem we have

$t=?\ years\\ P=\$4,500\\ A=\$7,020\\r=0.03$

The inequality that represented this situation is

$P(1+rt) \leq A$

substitute the values and solve for t

$4,500(1+0.03t) \leq 7,020$

$(0.03t) \leq (7,020/4,500)-1$

$t \leq [(7,020/4,500)-1]/0.03$

$t \leq 18.67\ years$

GCF of 9ab^2 and 6bc^2

garik1379 [7]

The GCF is 3*b = 3b

Step-by-step explanation:

The GCF is the Greatest Common Factor which will divide all the numbers whose GCF it is.

To find the GCF, we factorize the polynomials first

So,

$9ab^2 = 3*3*a*b*b\\6bc^2=3*2*b*c*c$

We can see that only 3 and b are common in factors of both polynomials

So,

The GCF is 3*b = 3b
