Please help me with this i dont understand it!!.

Step-by-step explanation:

Step One

Find the expression in the lower left square (the one on the left on the bottom row).

Lower Left Box on the bottom Row

2x + 3 + ax + b = 8x + 5          Subtract 2x from both sides

3 + ax + b = 8x - 2x + 5          Combine

3 + ax + b = 6x + 5                  Subtract 3 from both sides

ax + b = 6x + 5 - 3

ax + b = 6x + 2

a = 6

b = 2

6x + 2 goes into the lower left square.

Do the same thing to the lower right square

Contents of box on the lower right hand side on the bottom row.

2x + 3 + ax + b = 5x - 2       Subtract 2x + 3 from both sides

ax + b = 3x - 5

a = 3

b = - 5

3x - 5 goes into the lower right square.

So the circle is the sum of

6x + 2 + 3x - 5 = ax + b

9x - 3 = ax + b

a = 9

b = - 3

The circle with the question mark contains 9x - 3

i believe the answer is 68cm

step-by-step explanation:

i just took 34 x 2 because the space between v and y is the same as y to k.
