What is the sum of 8x^2-x+4 and x-5 is

8x^2-1

Step-by-step explanation:

8x^2-x+4+x-5=8x^2-x+x+4-5=8x^2+4-5=8x^2-1

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

2+2=4

4-5=-1
