giving brainliest! : )

5

Step-by-step explanation:

Those straight lines that seem as brackets are not brackets...but they are a sign called the modulus,which mean that if the value inside has to be multiplied by a negative...so hence..onto the solution;

| 4(-2) - 8 | + | -1 - (-2)^2 | + 2(-2)^3

; | -8 - 8 | + | -1 -4 | + (-16)

; |-16| + |-5| -16

; 16 + 5 - 16

;Therefore answer, 5

14 ft 7 inches

step-by-step explanation:

since each model inch corresponds to 25 real inches, 7 model inches will correspond to

7×25" = 175"
