1) {{{A = (1/2)BH}}} 
A = 56 sq. ins.
B = 14 ins.
Substitute these into the formula for the area.
{{{56 = (1/2)(14)H}}} Simplify and solve for H. Multiply both sides by 2.
{{{112 = 14H}}} Divide both sides by 14.
{{{H = 8}}}
The height is 8 inches.

2)
You are looking for two numbers, call them x and y.
Write the two equations that represent the problem.
x = 2y+5 Substitute this for x into the second equation.
x+y = 29
--------
(2y+5) + y =29 Simplify and solve for y.
3y+5 = 29
3y = 24
y = 8  Now substitute this into either of the two equations and solve for x.

x = 2(8)+5
x = 16+5
x = 21

The two numbers are:
21 and 8
