(1) A rectangle has sides of 3x-4 and 7x+10. Find the expression that represents its perimeter.

My answer for solving:

P=2L+2W

P=2(3w-4)+ 2(7x +10)

p=6w-6+14x+10

My final answer:

P=20x+12

P=2L+2W

P=2(3w-4)+ 2(7x +10)

p=6w-6+14x+10

2*-4 = -8 and not -6.

On the next term:

2*7x=14x as you have it BUT

2*10=20 and not 10

sorry they were typos. thank you.
