1) The length of one of the equal legs of an isisceles triangle is 8cm less than 4 time the length of the base. If the perimeter is 29 cm, find the length of one of the equal legs.
a) 4 cm
B) 5 cm
C) 11 cm
d) 12 cm

2) The perimeter of a rectangle is to be no greater than 300 in., and the length must be 125 in. Find the maximum width of the rectangle.
A) 20 in
B) 25 in
C) 50 in
D) 175 in

1. Solve these two eq
x + 2y = 29
y = 4x - 8

2.

2. 2x + 2y <or= 300
x = 125
250 + 2y <or= 300
2y <or= 50
y <or= ?

would the answer be 25?
