I need help, please asap

Step-by-step explanation:

A) Volume of box = lbh = 38*18*20=13680 cubic inches

Volume of player = 32*10*17  =5440 cubic inches

Space left  in the box =8240 cubic inches

B) No. packing cubes = Volume of suitcase/Volume of each packing cube

No. of packing cubes = 20

the highest percentage for deaths in construction from highest to lowest is as follows: falls, struck by objects, electrocution, and caught-in/between. these four are collectively known as fatal four.

in the case of falls, the type that is responsible for the overall highest death in the category is falls from roofs.

step-by-step explanation:

to determine whether a given function is even, we simply substitute x with -x in the expression. if the result after simplification is identical to the original equation, then the function is said to be even other wise odd.

f(-x) = (-x)^2 - (-x) + 8

      = x^2 + x +8

the resulting function is not identical to the original one;

f(-x) ≠ f(x)

therefore, f(x) is not an even function
