P = 2(L + W)
P = 292
L = 5W - 4

292 = 2(5W - 4 + W)
292 = 2(6W - 4)
292 = 12W - 8
292 + 8 = 12W
300 = 12W
300/12 = W
25 = W <=== width is 25 ft

L = 5W - 4
L = 5(25) - 4
L = 125 - 4
L = 121 <=== length is 121 ft

What is y=23x*45-7x+678 equal SHOW YOUR WORK (ONLY ANSWER IF UR AN ACE OR SYDNEETEAL) IF U DON'T KNOW DON'T ANSWER

Maksim231197 [3]

Answer:

x= $\frac{1}{1028} y$ + $\frac{-339}{514}$

Step-by-step explanation:

let's solve for x.

y=23x(45)−7x+678

step 1: flip the equation.

1028x+678=y

step 2: add -678 to both sides.

1028x+678+−678=y+−678

1028x=y−678

step 3: divide both sides by 1028.

1028x/1028=y-678/1028

x=1/028 y+-339/514

answer- x= $\frac{1}{1028} y$ + $\frac{-339}{514}$

good luck :)

have a great day !!
