Answer:

Step-by-step explanation:

Width = w

Length = w + 6

Area = 112 sq. cm

length * width = 112

(w +6 ) *w = 112

w² +6w -112 = 0

Sum = 6

Product = -112

Factors = 14 , -8 {14 - 8 = 6 , (-8)*14 = -112}

w² + 14w - 8w -112 = 0

w(w + 14) - 8(w + 14)=0

(w +14)(w -8) = 0 {Ignore w + 18 as measurement won't be negative}

w - 8 = 0

w = 8 ft

Length = 8 + 6 = 14 ft

kirza4 [7]

Answer:

Step-by-step explanation:

y = 3x - 5

6x + 3y = 15

Substitute the first equation into the second

6x + 3(3x - 5) = 15

6x + 9x - 15 = 15

15x = 30

x = 2

Then use the answer in the first equation and solve

y = 3(2) - 5

y = 6 - 5

y = 1
