An auditorium has a floor area of 20,000 square feet. the length of the auditorium is twice its width. find the dimensions of the room.

w = 100 ft , length = 200ft

Step-by-step explanation:

A = 2x * x => 2x^2

20,000 = 2x^2

10,000 = x^2

x = square root of 10,000 = + - 100

w = 100 ft , length = 200ft

180-142=38 for the acute angle next to the entry

90+38=128

180-128=52

a=52

step-by-step explanation:

if y=4x then you will substitute 4x in for y in the second equation.

8x + 4x = 18 combine like terms

12x = 18 divide by 12 on both sides

x = 18/12 or 3/2

now replace x in the first equation with 3/2 to get

y = 4 3/2

y = 6

the answer is a

(3/2,6)

hope that .
