Answer:
<h2>x = m - z</h2>
Step-by-step explanation:
z = m - x <em>add x to both sides</em>
z + x = m - x + x
z + x = m <em>subtract z from both sides</em>
z - z + x = m - z
x = m - z
Answer:
1500 ft^2
Step-by-step explanation:
The area of a triangle is 
, where b = base and h = height. In this triangle, we're given the base as 120 and the height as 25. 120 × 25 is 3000, and 3000 divided by 2 is 1500 ft^2.
Therefore, the answer is 1500 ft^2.

Answer:
Step-by-step explanation:
How many x-<em>intercepts</em>?
Factoring this polynomial eases the job of counting the intercepts.
f(x)=x^4-5x^2 = x^2(x^2 - 5)
Setting x^2 = 0 leads to two x-intercepts: (0, 0) and (0, 0) (a double root).
Setting x^2 - 5 = 0 yields the intercepts (-√5, 0) and (√5, 0).
Thus, there are, strictly speaking, FOUR x-intercepts. Of these, three are immediately visible.
