Answer:

The correct answer is

yes or no

Answer 2

Explanation:

4) let the number be x

thrice of x=3x

according to question

3x= x+8

=>3x-x=8

=>2x=8

=>x=8/2

=>x=4

so the number is 4.

5)(3n/5+7n)(3n/5-7n)

=(3n/5)^2-(7n)^2

=9n^2/25-49n^2

=(9n^2-1225n^2)/25

= -1216n^2/25

6)Given, volume of the container =0.9 m^3

1cm=1/100m

length of the container =50cm=50×1/100=0.5m

width of the container =120cm=120×1/100=1.2m

depth of the container =volume/(length ×width)

=0.9/(0.5×1.2)

=0.9/0.6

=1.5m
