X=-4+ square root 5/2
X=-7+ square root 5/2
X=-7 and x=-2
X=-1 and x=4

b

step-by-step explanation:

a

step-by-step explanation:

soo this can be solve by using the formula:

f = p( 1 + i)^ n

where f is the future profit

p is the initial profit

i is the percent increase

n is the number of years

a . f = 30000 ( 1.05)^n

b. f = 30000 ( 1.05)^15

f = $62,368
