10% of 140 is 14.
to solve you first must do 10/100 = 14/x
cross multiply and you get 10x = 1400
divide 1400 by 10 and you get 140
10x5 is 50, there is no hundreds place value
I consider "2(1+3g)" to be in its simplest form already. However, one could perform the indicated multiplication, obtaining 2 + 6g.

The length of a rectangle is seven less than twice the length of its width.
L = 2W - 7
A = W * L
A = 15
15 = W * L
Substitute the L in terms of W
15 = W * (2W - 7)
15 = 2W^2 - 7W
2W^2 - 7W - 15 = 0
Factorise:
(2W + 3) (W - 5) = 0
Solve for W:
2W + 3 = 0
2W = 0 - 3
2W = 3
W = 3/2
W = 1.5
W - 5 = 0
W = 0 + 5
W = 5
Use the original equation to find L:
L = 2W - 7
L = 2(5) - 7
L = 10 - 7
L = 3
L * W = 15
3 * 5 = 15
