Answer:
B
Step-by-step explanation:
Let the base of the triangle be <em>b</em> and the height be <em>h</em>.
The sum of the base and height is 14. Thus:

Recall that the area of a triangle is given by:

From the first equation, solve for either variable:

Substitute:

Distribute:

Distribute:

Let <em>b</em> = <em>x</em>. Hence:

Therefore, our answer is B.
Answer:
an irrational number
Step-by-step explanation:
35 is the answer to this equation I think
A circle with a diameter of 24 would have an area of 452.39. 452.39 rounded to the nearest hundred is 452.40.
