Answer:
5/32
Step-by-step explanation:
Since 5/8 x 1/4 = 5/32, that is the answer.
Key Note: When you get this type of question, multiply the second umber by the first.
Answer:
D
Step-by-step explanation:
BH is perpendicular to AC since an orthocenter is a point at which the three altitudes of a triangle intersect. The altitude of a triangle is that line that passes through its vertex and is perpendicular to the opposite side. Since you know that BH is an altitude due to Point H being an orthocenter, you know that BH is perpedendicular to AC.
p must be positive. If p is negative, the equation has no real solutions. This is because any number to the power of 2 is always positive. Therefore, if p is positive, there are 2 real number solutions: sqrt(p) and -sqrt(p).

The sum is 
.
Solution:
Given equation:
Using algebraic expression: 
To make the denominator same, multiply and divide the first term by (x –3)
Cancel the common factors.
; but x ≠ –3
If you substitute x = –3, the value is indeterminate.
Hence the sum is .
