Answer:

-1 /4 d - f

Step-by-step explanation:

Like terms imply that they have the same variables.

Therefore we grouped the "d"s together and the "f"s together.

1/2 d - 3/4 d + 3f - 2f

= (1/2 d - 3/4 d) + (3f - 2f)

= (1/2 - 3/4)d + (3 - 2)f

= -1 /4 d - f

Answer:

-1 /4 d - f

Step-by-step explanation:

1/2 d - 3/4 d + 3f - 2f

= (1/2 d - 3/4 d) + (3f - 2f)

= (1/2 - 3/4)d + (3 - 2)f

= -1 /4 d - f

top fin: 3x2.25/2=3.375, 3x0.75/2=1.125, 3.375+1.125=4.5

bottom fin: 1x1/2= 0.5, 1x0.5/2=0.25, 0.5+0.25=0.75

nose: 4.5x2=9

between tail and body: 2.5x2=5

corners on body: 1.5x0.5/2x4=1.5

top and bottom on body: 0.5x5x2=5

body: 1.5x2+5=8, 2x2=4, 4x8=32

total: 18+4.5+0.75+9+5+1.5+5+32=75.75
