Answer:

45 minutes

Step-by-step explanation:

Assume task completed in total x hours

\frac{x}{10} + \frac{3}{8} + \frac{3}{12} = 1 \\ 12x + 45 + 30 = 120 \\ 12x = 45 \\ x = \frac{15}{4} = 3 \frac{3}{4}

Answer:

4+2=6

15*6=90

9+9=18

18*3=54

90+54=144

Step-by-step explanation:

you have to add both the W and H together and then multiply them by the number of windows (4+2=6 , 16*6=90)

and the same with the garage doors (9+9=18, 18*3=54) then you take you two totals from multiplying and add them together (90+54=144)
