The largest area that can be enclosed will be that of a square (140 ft)/4 = 35 ft on a side. Such a square has an area of (35 ft)² = 1225 ft², not enough for the garden to be 1300 ft². This tells us the solution to the equation you're being asked to write is non-real.
_____
Putting the given numbers in the area equation, you have
... 1300 = 70w -w²
Multiplying by -1 and completing the square, we have
... w² -70w +35² = -1300 +35²
... (w -35)² = 1225 -1300 = -75
Taking the square root shows us the solution is non-real.
... w - 35 = ±√(-75) = ±5i√3
... w = 35 ± 5i√3 . . . . . . . . . after adding 35. These are complex solutions.
Answer:
C. 3
Step-by-step explanation:
8 / 1/3
When dividing fractions, do CCF (Copy, Change, Flip)
You keep the first number: 8
Change the division sign to multiplication: X
Flip the fraction to make it its reciprocal: 3/1
New expression:
8 X 3/1 or 8 X 3
Answer:
x>12
Step-by-step explanation:
its x is greater than 12
Mary spent $10.30 on dinner to stay in budget.
Step-by-step explanation:
Amount spent on breakfast = $6.25
Amount spent on lunch = $8.95
Amount spent on dinner = x
Average = $8.50
Average = 

Multiplying both sides by 3

Mary spent $10.30 on dinner to stay in budget.
