The area of a bulletin board is 55 ft2. The length is nine feet less than four times the width. Find the length and the width, i
galben [10]

Answer:

The length and width are 11ft and 5ft respectively

Step-by-step explanation:

let the

length = L

Width = W

Area = LW = 55

The length is nine feet less than four times the width

L = 4W - 9

W (4W - 9) = 55

4W^2 - 9W -55 = 0

4W^2 - 20W + 11W - 55 = 0

4W(W - 5) + 11(W - 5) = 0

(W - 5)(4W + 11) = 0

W - 5 = 0 , 4W + 11=0

W = 5 or  - 11/4

since the width cannot be negative, W = 5

LW = 55

L = 55/5

L = 11

The length and width are 11ft and 5ft respectively.

Answer:

b. \displaystyle 225y^2 + 150xy + 100x^2 = 225y^2 + 150xy + 100x^2

a. \displaystyle [8x + 12y]^2 + [6x + 9y]^2 = [10x + 15y]^2

Step-by-step explanation:

b. \displaystyle 225y^2 + 150xy + 100x^2 = 225y^2 + 150xy + 100x^2

a. \displaystyle [8x + 12y]^2 + [6x + 9y]^2 = [10x + 15y]^2

The two expressions are identical on each side of the equivalence symbol, therefore they are an identity.

I am joyous to assist you anytime.
