equation 2x2 - 7 = 9? Explain why you chose this

see explanation

Step-by-step explanation:

2x² - 7 = 9 ( add 7 to both sides )

2x² = 16 ( divide both sides by 2 )

x² = 8 ( take square root of both sides )

x = ± ← exact values

This method is useful when there are only numeric values to deal with

step-by-step explanation:

; fx

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
