Answer:
Combine like terms; 3x + 5x= 8x
Since you don't have any like terms for +8, it's going to remain the same and not change.
Answer : 3x + 5x + 8 = 8x + 8
Again with combining like terms, 4x + 4x = 8x
Answer: 4x + 4x = 8x
The third expression is going to be very similar to the last problem. 4x + 4x + 4x + 4x. We're going to add the terms together. 4+4+4+4 is equal to 16. Bring the x down and you get...
Answer: 16x
Lastly, we have -7x + 4 + 3x. Do the exact same thing we did to the other problems, combining like terms, shocking, I know. -7x + 3x= -4 and since there's no other like terms for +4, it stays the same. Therefore
Answer: -7x + 4 + 3x = -4 + 4

Answer:
6x
Step-by-step explanation:
2x*3x=6x
We can set up the width a X and, from the description the length would be 3X-1. The perimeter of a rectangle is determined by 2XL + 2Xw. Plugging into the equation 2(3X-1) + 2(X) = 118. Next distribute to get 6X-2 + 2X = 118. Combine like terms to get 8X = 120. Divide by 8 to get X = 15. The width is 15. The length is 3(15)-1 or 44. 88 +30 = 118
