Group like terms, in this case terms with variables and terms without. (m + 11) + (n + 44) = (m + n) + (11 + 44) Then simplify. (m + n) + (11 + 44) = (m + n) + 55 = m + n + 55 Final answer: m + n + 55

Let w represent the width of the rectangle in cm. Then its length in cm is (3w+9). The perimeter is the sum of two lengths and two widths, so is ...
... 418 = 2(w + (3w+9))
... 209 = 4w +9 . . . . . . divide by 2, collect terms
... 200 = 4w . . . . . . . . subtract 9
... 50 = w . . . . . . . . . . divide by 4
... length = 3w+9 = 3·50 +9 = 159
The dimensions of this piece of land are 159 cm by 50 cm.

Answer:
C = 100 degrees
B = 70 degrees
Step-by-step explanation:
OPPOSITE ANGLES OF A CYCLIC QUADRILATERAL ARE SUPPLEMENTARY, WHENEVER YOU ADD THEM THEY SHOULD GIVE YOU 180 DEGREES.
SOLUTION
A + C = 180
80 + C = 180
C = 100
D + B = 180
110 + B = 180
B = 70
