Answer:The answer can be calculated by doing the following steps;
Step-by-step explanation:
I don't understand these problems
1 answer:
So given the values on the number line, AB and BC, adding them together will get the length of AC. If AB equals 
and BC equals 
, the value of AC should be 
. Since you are given the length of AC, 
, you can create an equation to solve for x. This equation would be 
. Isolating the x on the left (or right hand side) gets the value of x to be 19. The same thing goes for the 2nd question.

The value of p if the pair of equations may have one root common is 1.
<h3>What are the roots of the equation?</h3>Let the equation be ax² + bx + c = 0.
Then the roots of the equation will be
The equations are given below.
2x² + px - 1 = 0 and 3x² - 2x - 5 = 0
The roots of the equation 3x² - 2x - 5 = 0 will be
3x² - 5x + 3x - 5 = 0
(3x - 5)(x + 1) = 0
x = -1, 5/3
At x = -1, the value of p will be
2(-1)² + p(-1) - 1 = 0
2 - p - 1 = 0
p = 1
The value of p if the pair of equations may have one root common is 1.
