Problem #32
Directions: simplify by combining like terms.
sqrt 63 - 2sqrt 28 + 5sqrt7
ans = sqrt(7*9)- 2sqrt(4*7)+ 5 sqrt(7)
= 3 sqrt(7)-4 sqrt(7)+5 sqrt(7)
= 4sqrt(7)
Problem # 50
Directions: Find the perimeter of the triangle shown in the figure.
the triangle has for the hypotenuse leg= 4
height leg = sqrt 5 - sqrt 3
base leg = sqrt 5 + sqrt 3
answe is 2sqrt5 + 4
