In the graph below the vertices represent houses and two vertices are joined by an edge of it is possible to drive between the houses in under 10 minutes, find a path from a to g that would take under 20 minutes

area of part 1:

a1=base*height/2=(8+2)*(8-2-2-1)/2=10*3/2=15 ft^2

area of part 2:

a2=length*width=(8+2)*1=10 ft2

area of part 3:

a3=length*width=8*2=16 ft2

total shaded area : a1+a2+a3=41 ft2

total area of the reactangle : a=16*8=128 ft2

total area of the nonshaded region : 128-41=87 ft2

step-by-step

-2x + 7 = 7

subtract 7 from both sides.

-2x = 0

divide both sides by -2.

x = 0

it would take 5 hours i think idk i'm not that good at math.can you me with my questions i need asap.
