Given the points As1, 0, 1d, Bs2, 3, 0d, Cs21, 1, 4d, and Ds0, 3, 2d, find the volume of the parallelepiped with adjacent edges AB, AC, and AD.

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:

a variable is any characteristics, number, or quantity that can be measured or counted. a variable may also be called a data item. hope i !

so, converting firstly the mixed fractions to improper fractions and then "adding".

$4034.40

the perimeter of the field is the sum of the lengths of the four sides:

47 yd + 158 yd + 47 yd + 158 yd = 410 yd

the cost of 3 ft (1 yd) of fence is 3×$3.28 = $9.84.

so the cost of jake's wood perimeter fance is

(410 yd) × ($9.84 /yd) = $4034.40
