Answer:
If those are absolute value lines: 22 and -64
Step-by-step explanation:
43 = | c + 21 | is an absolute value equation, meaning it has two answers.
To get the first you keep 43 positive and remove the absolute values and solve normally: 43 = c + 21 -> 43 - 21 = c -> c = 22.
To get the second you make 43 negative and remove the absolute values then solve: -43 = c + 21 -> -43 - 21 = c -> c = -64
43 = 22 + 21 -> 43 = 43
43 = -64 + 21 -> 43 = 43

Factor x^4-y^4: (x²+y²)(x²-y²)
further factor: (x²+y²)(x+y)(x-y)
so the dimensions are (x²+y²)(length), (x+y) (width), and (x-y) (height)
The volume is 13*7*5. Therefore, the answer is 455 in^3

Well, if Sameer's plum was 32 calories, and we know his total snack was 56 calories, all we have to do is:
56-32=24
24 / 4 = 6
Sameer ate one plum (32Kcal) and 6 strawberries (4Kcal each)
