You can put this solution on YOUR website! Excuse me!! You CAN do something to this!
(7a)(9b), you are essentially multiplying two numbers times two more numbers, so actually 4 numbers are being multiplied together. You can multiply any two of those togther, as you choose. So, multiply the 7 times 9 and then times the a and times the b. The net result is 63ab.
Final answer: 63ab
