Answer: D they are congruent because they all have the same angle measures.
Step-by-step explanation:
Answer:
Dimensions: 150 m x 150 m
Area: 22,500m²
Step-by-step explanation:
Given information:
- Rectangular field
- Total amount of fencing = 600m
- All 4 sides of the field need to be fenced
Let
= width of the field
Let
= length of the field
Create two equations from the given information:
<u>Area of field</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 Tanya the maximum area are:
150 m x 150 m
The maximum area is:

Answer:
I think the answer is no.D In my opinion
F(x)=2x+8
G(x)=x-4
Plug g(x) into f(x)
F(g(x))=2(x-4)+8
Distribute
F(g(x))=2x-8+8
Simplify
F(g(x))=2x
Answer:
yes it square root is irational
