1.Simplify the expression by combining like terms.

2x + 4x - 5x + 2y

2. The expression

[b²+d²+ (b+d)s]

can be used to find the total surface area of the trumpet mute shown. Evaluate the expression for the given dimensions to find the number of square inches of cardboard (to the nearest tenth) used to make the mute. (Assumeb=3,s=9, andd=3.5.)
