x² – 6x= 5
Answer:
x = 8.7 or x = 1.3
Step-by-step explanation:
x² – 6x= 5
(b/2)² = (6/2)² = 9 (Using Completing the square method)
x² – 6x + 9 = 5 + 9
(x -5)² = 14
x-5 = √14
x-5 = ±3.7
Either x-5 =3.7 or x-5 = -3.7
x = 3.7+5 or x = -3.7+5
x = 8.7 or x = 1.3
B) 120 square yards
C) 60 square yards
D) 40 square yards
Answer: D) 40 square yards
Step-by-step explanation:
We know that 1 yard = 3 feet
Given that Area of Austin's office = 360 square feet
To find the area of his office in square yards, we need to divide the given area by square of 3.
We know that square of 3=
Thus, the area of his office in square yards=
Hence, the area of his office in square yards=
That is wrong i was taking a test the answer is going to be 40 square yards
