Answer:
X=-2or,-3
Step-by-step explanation:
X^2+5x+6=0
or,x^2+(2+3)x+6=0
or,x^2+2x+3x+6=0
or,x(x+2)+3(x+2)=0
or,(x+3) (x+2)=0
Either,
x+3=0 x+2=0
or,x=-3 or,x=-2
Therefore,the value if x is -2 or -3 .

Say x = 12 and y = 4
12 - 4 = 8
Number 1
2(12) - 4(4) = 8
24 - 16 = 8
Number 1 is your Answer
Answer:
Dimensions: 125 m x 250 m
Area: 31,250 m²
Step-by-step explanation:
Given information:
- Total amount of fencing = 500m
- Only 3 sides of the land need to be fenced
First, let us assume that the land is <u>rectangular</u> in shape.
Let
= length of the side opposite the river
Let
= length of the other 2 sides of the land
Therefore, we can create two equations from the given information:
<u>Area of land</u>: 
<u>Perimeter of fence</u>: 
Rearrange the equation for the perimeter of the fence to make y the subject:

Substitute this into the equation for Area:

To find the value of x that will make the area a <em>maximum</em>, <u>differentiate</u> A with respect to x:

Set it to zero and solve for x:

Substitute the found value of x into the original equation for the perimeter and solve for y:

Therefore, the dimensions that will give Christine the maximum area are:
125 m x 250 m (where 250 m is the side opposite the river)
The maximum area is:
