2x^2 + ax = x(2x+ 7)

Subtract 2x^2 from both sides
ax = 7x
a = 7

A computer costs $800. It loses ¼ of its value every 2 years after it is purchased.
Rufina [12.5K]

The computer will be worth $200.

Step-by-step explanation:

A quarter of $800 is $200, so the computer loses $200 dollars in value every two years. Since 6÷2 is 3, you multiple $200 by 3 to get $600. You then subtract $600 from $800 and get $200.
