Answer 1

Answer:

The right answer

because it is meantioned

Answer 2

Answer:

1)

$=\frac{125*3^{5}*9 }{5^{2}*3^{6} } \\=\frac{5^{3} *3^{7} }{5^{2}*3^{6} }\\=\frac{5^{3} *3^{7} }{5^{2}*3^{6} }\\=5^{3-2} *3^{7-6} \\=5*3\\=15$

2)

$= x^{2} +5xy - (x^{2} +3xy-y^{2})\\= x^{2} +5xy - x^{2} - 3xy + y^{2}\\= x^{2} - x^{2} +5xy - 3xy + y^{2}\\= 2xy + y^{2}$

3)

Perimeter = 2(l+b)

= 2(70 + 50)

= 2(120)

= 240m

4)perimeter = side*4

240 = side * 4

side = 240/4

side = 60

Area = side*side

= 60*60

= 3600m square
