The angles diagonally opposite each other are congruent while those adjacent to each other add up to 180 degrees. You can get eight congruent angles with a transversal if the two lines are parallel, because each angle would be 90.

Answer:
a(x)=2x^2+9x+4
Step-by-step explanation:
We have been given the length and width, as well as the formula to find the area:
Length: 2x + 1
Width: x + 4
A = l * w
A = (2x + 1)(x + 4)
2x^2 + 8x + x + 4
We can add like terms now:
2x^2 + 9x + 4
Our area is 2x^2 + 9x + 4
Our answer would be a(x)=2x^2+9x+4
Answer:
The temperature of the chemical solution after t hours is 
Step-by-step explanation:
Given that the initial temperature of the chemical solution, 
.
The rate of decreasing temperature, 
So, after t hours, the temperature of the chemical solution will decrease by 
.
So, the temperature of the chemical solution after t hours,
Hence, the temperature of the chemical solution after t hours is 
.
