Imagine a 'U' shape
sides are x legnth
base is b legnth
2x+b=25
area is height times base=xb
xb=50
2x+b=25
solve
minus 2x both sides
b=25-2x
sub for b
x(25-2x)=50
25x-2x^2=50
times -1 both sides
2x^2-25x=-50
add 50 both sides
2x^2-25x+50=0
use quadratic formula or something
x=2.5 or 10
A is the answer
50/8 can be simplified by dividing top and bottom by 2, getting 25/4. this is also equal to 6 and 1/4
Answer:
(B)1059.265 deer per square mile
Step-by-step explanation:
Population Density in Clinton County = 23 deer per sq. mile.
Area of state of Pennsylvania = 46.055 sq miles
Since the population density of deer in the entire state of Penn. is the same as in Clinton County.
Population Density of deer in Pennsylvania = 23 deer per sq. mile.
Population Density = Number of Deers/Area of the Region
23 = x/46.055
Cross Multiplying
x=23 X 46.055
=1059.265 deer per square mile
There are 1059.265 deer per square mile in Pennsylvania.
All the fractions are factors of 30
1/3 X 10, 1/5 X 6, 1/2 X 15.
/\10/30, /\6/30, /\15/30
Add all of them together: 31/30
Then you simplify the total: 1+1/30
1 and 1/30 is the answer
Answer:
here, in this question given the value of X will be 1 and the value of y will be (-2)
but (-2) =5-3(1)
(-2)=/ 2
so (1,(-2)) is not the solution of the given equation
