Answer:

p/q = 126/99

Step-by-step explanation:

0.27 is a repeating decimal. It goes out to infinity.

100n = 100*1.272727272727 ... to infinity

100n = 127.272727272727 ... to infinity

n = 1.272727272727 ...... to infinity Subtract

99n = 126 The rest cancels out

n = 126/99 Answer

PSYCHO15rus [73]

The expression that represents the width and length of the square is (x+10).

We factor this expression to find the dimensions. We want factors of 100 that sum to 20; 10(10) = 100 and 10+10=20. This gives us

(x+10)(x+10).
