Answer:

Add like Terms

Subtract -5m²+6m-10 from the sum of 2m²-m+4 and 4m²+6m-8

First Step:

(2m²-m+4+4m²+6m-8)-(-5m²+6m-10)

=(6m²+5m-4)-(-5m²+6m-10)

Second Step:

(6m²+5m-4)-(-5m²+6m-10)

=11m²+11m-14

1.) What is the perimeter of a square whose sides measures (2x+1)?

• What is asked in the problem:
• The total number of perimeter of a square whose sides measures (2x+1).

• What is the given in the problem:
• side=(2x+1)

• What is the formula for the perimeter of the square:
• P=4S

• Solution:
• p=4s
• p=4(2x+1)
• p=8x+4

• Answer:
• 8x+4
