9514 1404 393

  30x³ -12x² +18x

Step-by-step explanation:

The perimeter of an equilateral triangle is three times the side length:

  P = 3s

  P = 3(10x³ -4x² +6x)

  P = 30x³ -12x² +18x . . . . the triangle perimeter

13

step-by-step explanation:

169-1=168

168-3=165

165-5=160

160-7=153

153-9=144

144-11=133

133-13=120

120-15=105

105-17=88

88-19=69

69-21=48

48-23=25

25-25=0

since it took 13times to completely subtract it hence its square root is 13

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
