x = _________

Answers

Answer 1
Answer: x = -b/2a
so substitute the numbers inside the it gives
x = -(-10)/2*5
x = 10/10

A farmer decides to enclose a rectangular garden, using the side of a barn as one side of the rectangle. What is the maximum area that the farmer can enclose with 80 feet of fence? What should the dimensions of the garden be to give the area?

Answers

garden
max area is if the sides are as equal as possible
so he should try to make a square (ideal is a circle, but barn walls are normally straight)
squaer perimiter=4 times legnth of 1 side
perimiter=amount of fencing=80
80=4s
divide 4
20=s
one sides=20

area=legnth times width
in squaer, legnth=width

20=legnth
20=width
area=20 times 20=400

dimetions are 20ft by 20ft to give 400ft^2
(fun fact, if it were a circle, the area would be about 509.5ft^2)


answer is 20ft by 20ft and area=400ft^2

Answer to 1+4=5 2+5=12 3+6=21 8+11=?

Answers

It appears that each consecutive answer is added to the next operation such that  ((1+4)=5)+2+5=12, because 2+5=7, but when added to (1+4), the answer is 12, and so on. 

Thus, 
(1+4)=5 + (2+5)=12 + (3+6)=21 + (8+11)=40
the answer will be 19

Yesterday my family caught a largo fish. We ate 2/6 of the fish. Today we eat 2/4 of the fish. Told my motores that we ate more fish yesterday than today because 6 is greater than 4. So 2/6 is greater than 2/4. My mother told me i madre a mistake .

Answers

Answer:

Step-by-step explanation:

Fraction of fish ate on first day = 2/6

fraction of fish ate on second day = 2/4

In case of comparison of rational numbers if the numerators of two rational numbers is same and the denominators are different, then the number having larger denominator is less than the number having smaller denominator.

So, the number 2/6 < 2/4

So, the fraction of fish ate on the first day is less than the amount of fish ate on te second day.

Which represents the equation of the line?

Answers

Answer:

D: y= -2x -1

Step-by-step explanation:

The line crosses the y axis at -1 and using the "rise over run" phrase you can tell that the next point is 2 up and 1 over (2/1 =2) the line is also negative because it moves down from left to right. Therefore, y= -2 -1
