First you need to multiply the one in the bracket 7x2 which is 14 then u must multiply it with 3 to get the answer so 14x3 which equals to 42
Split it into 7 triangles. Half-base of each is 2 so the distance of center to the midpoint of the base is (Pythagoras) square root of (4.62 - 22) = 4.162 triangle is this times 2, and with 7 triangles multiply also by 7 to get an approximate area of 58 sq in.
Absolute value means ignore negative signs, so #38 is asking is 282 greater or less than 279. it's greater. #39 is negative of |-10| the absolute value signs work as parentheses too, so it's -(10) so -10
X equals weight of permit fish
x + 10X = 132
11x = 132
x= 12
permit fish= 12
tarpon=120
