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
I hope this helps, mark as brainliest, please? :)
Answer: The answer is (D) 
Step-by-step explanation: Given that there is a rectangle, where length of the rectangle is given by

and width of the rectangle is given by

We are to find the perimeter of the rectangle. To do so, we need to add two times length with two times breadth of the rectangle.
Therefore, perimeter is given by

Thus, the correct option is (D).
Answer:
26.14
Step-by-step explanation:
For the triangles: 3*4=12
For the circle: 28.27/2=14.135
12+14.135=26.135
~26.14
