Answer:

11,400 ft^2

with no allowances for doors or windows

Step-by-step explanation:

ceiling: (35)(40) = 1400

walls: 2(35 x 16) + 2(40 x 16) = 2400

2400 = 1400 = 3800 ft^2

3800 ft^2 x 3 = 11,400 ft^2

What are the roots of this quadratic equation? 3x^2+10=4x
____ [38]

Step-by-step explanation:

The root of an equation is when x=0.

We need to rewrite this as 3x²-4x+10=0.

The quadratic formula is

(-b+or-sqrt(b²-4ac))/2a

so 4+or-sqrt(16-120)/2a

since the sqrt can no be negative this answer will have imaginary numbers.

(4+2i sqrt(26))6 and (4-2i sqrt(26))6

simplified is

x=(2+i sqrt(26))/3 and x=(2-i sqrt(26))/3

There are 19 animals on the farm which contains hens and goats. There are 68 legs in total. How many goats are there on the farm
Masteriza [31]

Answer: 15 goats

Step-by-step explanation:

h = hens - they have 2 legs

g = goats - they have 4 legs

The equations would be:

h + g = 19

2h + 4g = 68

To solve this, I personally prefer substitution, we're isolating h since we need to find g:

h + g = 19

h = 19 - g

Now that we have h, we can plug this into the second equation:

2h + 4g = 68

2(19 - g) + 4g = 68

38 - 2g + 4g = 68

2g = 30

g = 15

There are 15 goats.

Adding onto this, 19 - 15 = 4, so there are 4 hens.
