Irst you multiply 2 both sides
2A=h(a+b)
then divide each side by a+b
2A/(a+b)=h
that's the simplified equation

Answer:
$1380
Step-by-step explanation:
- The regular price of a computer is $1200
- The regular price of a printer is $300.
The electronics store offers a 40% discount on the printer only when the computer is purchased at the regular price.
Discount on the Printer = 40% of $300 =0.4 X 300 =120
Promotional Price of the Printer = $300-120 =$180
Therefore, the total cost of the computer and the printer at the promotional price
=Regular price of a computer + Promotional Price of the Printer
=1200+180
=$1380
