An expression is shown below: 4(m + 3 + 5m) part a: write two expressions that are equivalent to the given expression. 2(2m+6+10m) 4m+12+20m part b: show that one of your expressions in part a is equivalent to the given expression using algebraic properties. explain which properties you used. part c: show that your other expression from part a is equivalent to the given expression by substituting a number for m.

complete the steps to find the area of the trapezoid.

area of rectangle = 256   square units

area of triangle 1 = 24  square units

area of triangle 2 = 16  square units

area of triangle 3 =   96 square units

area of trapezoid = 120  square units

step-by-step explanation:

maximum area = xy = (16)(32) = 512 ft2

to maximize the area of the garden, the side of the fence parallel to the side of the house should be 32 ft long, and the other two sides should both have length 16 ft.'
