Someone i’m begging you give me the answers to these 6 problems i’ll give u the highest points possible

Hello from MrBillDoesMath!

* I only have time to help you with 3 problems. *

1. SWIMMING:   total number of laps = 10x-3

3.  BEDROOM: Perimeter = 6x +2

4. HOCKEY: Total number of goals =  6x + 1

Discussion:

1. SWIMMING:

The total number of laps swam all 4 weeks is the sum of the laps from each week:

(x+2) +  3x + (2x+1) + (4x-6) .

Separate and combine "x" terms and constants

(x + 3x + 2x + 4x) + (2 + 1 -6) =

10x + (3-6)  or   10x - 3

3.  BEDROOM

Imagine you are at one corner of the rectanle and you walked all the way around to rectangle back to your start point. That distance gives the perimeter.

Perimeter =  (2x-3) +  ( x + 4)   + (2x-3) + ( x+4)

                 = ( 2x + x + 2x + x ) + ( -3 + 4 -3 + 4) =

                =  6x +2

4. HOCKEY

Total number of goals = sum of goals from all three games =

 2x + (x+2) +  (3x - 1) =

(2x + x + 3x) + (2 - 1) = 6x + 1

Thank you,

MrB

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
