The equation 0 = -2x2 5x - 3 was the quadratic formula that Zacharias used. However, he started substituting as:
Quadratic formula as x = ; substitution as x
The errors he made: he mistakenly used the negative (-) and postive (+)
* -5 should have been 5
* 52 should have been -52
* both the numerator and the denominator should have been -2 instead of 2

Answer:
91.46m
Step-by-step explanation:
The length of 100 yard football field in meters.
From the dimension given,
1 yard = 3 feet
Therefore,
100 yard = x feet
1 yard = 3 feet
100 yard = x feet
X = (100 × 3) / 1
X = 300 feet.
But,
1 metre = 3.28feet
X metre = 300 feet
X = (300 × 1) / 3.28
X = 91.46m
Therefore, 100 yard football field is equal to 91.46m
Answer:
110 / 3.6 = 30.555
Chance for yellow is about 31%
Orange is 70/3.6= 19.4444444
Orange is about 19%
Red is 40/3.6=11.11
Red is about 11
We divide by 3.6 because 360 degrees /100 percent = 3.6
The decimals are repeating so it is infinite decimal places
Yellow is about 31% (30.555555 for exact)
Orange is 19%(19.4444444 for exact)
Red is 11%(11.11111 for exact)
Step-by-step explanation:
Lawns = L
Money he gets from mowing = M
