Step-by-step explanation:
(12x - 19y) (12x + 19y) = 144x^2-361y^2
52+52=110
182-110=72
72 / 2 =36
the width is 36
Answer:
x=16 and y=9
Step-by-step explanation:
2y+30=3y+21[Diagonals of parallelogram are equal]
30-21=3y-2y
y=9
3y=2x-5[Diagonals of parallelogram are equal]
3×9=2x-5
27=2x-5
2x=27+5
x=32/2=16
