A scale drawing of a patio is shown at right. The scale is 4 inches : 6.8 feet. What are the length and width of the patio? Find the patio’s area. A) 25.5 ft; 23.8 ft; 606.9 ft2
B) 25.5 ft; 23.8 ft; 609.6 ft2
C) 25.5 ft; 28.3 ft; 606.9 ft2
D) 21.5 ft; 24.8 ft; 686.9 ft2

ad = ae + ed = y + 7

similar triangles therefor

ac/ab = ad/ae

6/4 = (y + 7) / y

cross multiply

6y = 4(y + 7)

6y = 4y + 28

2y = 28

y = 14

step-by-step explanation:

d

step-by-step explanation:

given

y + 3 = - 4(x - 2) ← distribute the parenthesis

y + 3 = - 4x + 8 ( subtract 3 from both sides )

y = - 4x + 5 → d
