Answer:
A.
Step-by-step explanation:
x2 - 3x - 10. = 0
x2 + 2x - 5x - 10 = 0
(x2 + 2x) (-5x - 10) = 0
x (x + 2) - 5 (x + 2) = 0
(x - 5) (x + 2) = 0
x - 5 = 0 x + 2 = 0
x = 5 or x = - 2.

Step-by-step explanation:
Yes it can be. There are more than just right triangles but all right triangles are scalene
Let us set up an equation, to determine the list price. X represents the original price
.12 * x = 25
In order to solve for X, you must divide .12 from both sides
x = 25/.12
After you divide, you should get the number 208.33
25/.12 = 208.33
So, the original list price is $208.33

Step-by-step explanation:
Given a long algebraic equation, the like terms can be collected. When you collect like terms, you reduce the length of the algebraic equation.
After that, you can factorize the equation where possible. When you factorize the equation. It becomes quite easier to solve it efficiently.
