Answer:
72
Step-by-step explanation:
for the rectangles you use the formula :
a=lw 3x6=18x2=36 + 4x6=24
and for the triangles you use:
a=1/2bh 3x4=12/2 + 3x4=12/2
then you add it all together
36+24+12=72
Y + 6 = 4/5( x + 3)
y + 6 = 4/5x + (3(4))/5
y + 6 = 4/5x + (12)/5
y + 6 = 4/5x + 12/5
y + 6 (-6) = 4/5x + 12/5 (-6)
y = 4/5x + 12/5 (- 30/5)
y = 4/5x - 3.6 ( y = mx + b formula)
4/5 = 0.8
y = 0.8x - 3.6
x = 1
y = 0.8(1) - 3.6
y = - 2.8
x = 2
y = 0.8(2) - 3.6
y = 1.6 - 3.6
y = -2
x = 3
y = 0.8(3) - 3.6
y = 2.4 - 3.6
y = - 1.2
x = 4
y = 0.8(4) - 3.6
y = 3.2 - 3.6
y = - 0.4
x = 5
y = 0.8(5) - 3.6
y = 4 - 3.6
y = 0.4
etc.
