Dorothy can type 120 words per minute. Which can also be represented by
120 x 1 (minute)= 120
If you want to know how many words it takes her for 1.75 minutes, simply multiply 120 by 1.75.

Answer:
136 in
Step-by-step explanation:
Assuming the figure is a square with equal sides, then
4x - 2 = 3x + 7 ( subtract 3x from both sides )
x - 2 = 7 ( add 2 to both sides )
x = 9
Thus side = 3x + 7 = 3(9) + 7 = 27 + 7 = 34
Thus
perimeter = 4 × 34 = 136 in
