Question 821775
2)SOLVE THE EQUATION (2* lg x +lg 3 = lg 48)
log(x^2) + log(3) = log(48)
---
log(3x^2) = log(48)
3x^2 = 48
x^2 = 16
x = 4

03) a hollow prism wuth a cross setion in the shape of an eqilateral traingke has been made by folding a rectangular piece of paper.the surface aea of the prism is 450cm squared.and it's length is 30 cm .find the length of a side of it's cross section?
-----
Area of each side of the prism = 150 cm^2
LW = 150
30W = 150
Width = 5 cm
