Since PQ = QB, PB = 2PQ = AP. Thus P is the midpoint of AB, and Q is the midpoint of PB. Then the midpoint (X) of QB is AP + PQ + QX = 1/2 + 1/4 + 1/8 times the length of AB from A.

The distance from A to the midpoint of QB is (7/8)a.

Explain or show work to prove that the following equation is true.6 x 8 = 3 x 2 x 2 x 2 x 2
mr Goodwill [35]

Answer:

see explanation

Step-by-step explanation:

To prove the equation id true, solve both sides and if they are equal then the equation is true.

left side = 6 × 8 = 48

right side = 3 × 2 × 2 × 2 × 2

               = 6 × 2 × 2 × 2

              = 12 × 2 × 2

              = 24 × 2

=             = 48

Since both sides are equal then the equation is true
