Length (L) = width (B) + 6

Area = L x B

432^2 = (B + 6) x B

432^2 = B(B + 6)

Alternatively

432^2 = B^2 + 6B

Answer: Width = 24 inches

Step-by-step explanation:

Let W represent the width of the rectangular sign.

The length of a rectangular sign is 6 inches more than half its width. It means that the length of the rectangular sign would be

W/2 + 6

The formula for determining the area of a rectangle is expressed as

Area = length × width

The area of the sign is 432 square inches. Therefore, the equation for the area of this sign would be

W(W/2 + 6) = 432

W²/2 + 6W = 432

Multiplying both sides of the equation by 2, it becomes

W² + 12W = 864

W² + 12W - 864 = 0

W² + 36W - 24W - 864 = 0

W(W + 36) - 24(W + 36) = 0

W - 24 = 0 or W + 36 = 0

W = 24 or W = - 36

Since W cannot be negative, then

W = 24

Find the value of x that makes the equation true<br> 3(-2 + 1 ) + 5 = 3x -4 - 5x
miv72 [106K]

Answer:

x =  - 3

Step-by-step explanation:

Reason

3( - 2 + 1) + 5 = 3x - 4 - 5x \\ open \: the \: bracket \: at \: the \: lhs \\  - 6 + 3 + 5 = 3x - 4 - 5x \\ 2 = 3x - 4 - 5x \\ collect \: like \: terms \\ 2 + 4 = 3x - 5x \\ 6 =  - 2x \\ 2x =  - 6 \\ divide \: both \: sides \: by \: 2 \\  \frac{2x}{2}  =  \frac{ - 6}{2}  \\ x =  - 3
