Let
Then
and solving for x gives
By the quadratic formula,
but x must be a positive number, so only the positive square root solution is valid.
We identify a = c = 3 and b = 2, so a + b + c = 8.
Answer:
2 Gallons
Step-by-step explanation:
20.5ft x 16.4ft = 336.2
336.2 divided by 200= 168 gallons
Since you can not buy 1.68 gallons you will have to buy 2 galllons instead.
The equation will be
8 / 2 = 4
In the repeated subtraction since in actuality division is the larger numbers which is just subtraction.
it becomes,
8 - 2 -2 = 4
8 -2 = 6 - 2 = 4
The answer to this question is C
3
the area is 41.6cm which is 1foot 4 3/8 inches.
So 6in + 6in + 6in = 1ft 6in, which will be enough to cover the floor.
