Ineed with the blanks. this geometry proofs.

Step-by-step explanation:

First problem:

blank 2) on the left: PR = PQ + QR

blank 3) on the right: Replace PR in statement 1) with what we just completed in statement 2. Therefore:

2PQ = PR

2PQ = PQ + QR

blank 4) on the right: Subtract PQ from both sides, therefore

2PQ = PQ + QR

2PQ - PQ = PQ + QR - PQ

PQ = QR

in the math equation 8 x 7 = 56, the 8 and the 7 are both factors of 56, since in this lesson we will use square tiles to figure out the factors of a whole find as many different arrays as you can, but follow one important rule: all the rows must have the i can make two rows of nine, so 2 and 9 are both factors of 18.
