John has to solve the equation 3x = 15. What should John do the the equation? A. John should divide both sides of the equation by 3.
B. John should multiply both sides of the equation by 3.
C. John should add 3 to both sides of the equation.
D. John should subtract 3 from both sides of the equation.

multiply length by height. multiply the length by the height, and then double the product. work out 10 x 10 results = 100 square inches, then work out 100 x 2 = 200. the answer is 200 square inches.

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
