Let the larger number X and the smaller be y then ,


3y+5 = x ...1
x-y = 35 ....2

From 2 -> x = 35+y

Putting its value in 1 3y+5 = 35+y
3y-y = 30
y = 30/2 = 15 .

Putting y's value in 2 ->
x = 35+15
= 50

-8a^3b + 3a^2b^2 - 5 + (2 + 5a^2b^2) + (3a^3b + 7 - 9a^2b^2)
= -8a^3b + 3a^3b + 3a^2b^2 + 5a^2b^2 - 9a^2b^2 - 5 + 2 + 7
= -5a^3b - a^2b^2 + 4

The hypotenuse of a right triangle is 25 cm, and the shorter leg is 15 cm. The length of the other leg is 20cm.
Let the other leg is d
d^2 = 25^2 - 15^2
d^2 = 625 - 225
d^2 = 400
d = 20
