This is the formula you want to use:
It means that length·width·height = Volume. So, 5 · 4 · 3 = 60 ft.
Answer:
Step-by-step explanation:
For a, you need to plugin -9 into the equations inside the boxes and solve.
y = x^2 + 3, y = 9^2 + 3, y = 81 + 3, y = 84.
y = √x - 2, y = √9 - 2, y = 3 - 2, y = 1.
For b, It's only possible for the second equation to output 0, as for the first, it's impossible for x^2 to equal -3 and add to 3 to get 0. For the second equation you can plug in 4 to get 2 - 2, which gives 0.
