Answer:

-43

Step-by-step explanation:

f(-3) = 4(-3) - 7 = -12 - 7 = -19

g(4) = -7(4) + 4 = -28 + 4 = -24

-19 + (-24) = -43

Please help wit all questions! leave work below! if you do this , it will give you 40 points!!
Marta_Voda [28]

Answer:

13. ft per minute is 150. ft per hour is 9,000.

work:

  • 300÷ 2 = 150
  • 150 times 60 min.

14. x ÷ y = feet per minute.

it is this because the time divided by the depth will equal the time that it took.

15. it would be more reasonable to use feet by minute, because of the accuracy of the answers. with measuring it using feet per hour, your answers will be less precise.

16. the distance will double because the proportional relationship says that the distance is 3 km away if thunder is 9 secs apart from lightning.

will answer next question later

Colt1911 [192]

9514 1404 393

Answer:

  27 cm³

Step-by-step explanation:

The surface area of a cube is ...

  SA = 6s²

Then the edge length is ...

  54 cm² = 6s² . . . . . please note that cm³ is not the appropriate unit for area

  9 cm² = s² . . . . . .divide by 6

  3 cm = s . . . . . . . take the square root

The volume of a cube is ...

  V = s³

  V = (3 cm)³ = 27 cm³

The volume of the cube is 27 cm³.
