GIVING BRAINLEST!!!Joe and Tim observed two points, P and Q, on a number line. A number line is shown from negative 1 to positiv
Veronika [31]

Answer:

Step-by-step explanation:

P is 5 ticks to the left of 0, so it would be -5/8

Q is 5 ticks to the right of 0, so it would be at 5/8

 an absolute value turns a negative number into a positive number

 so absolute value of  P located at -5/8 = 5/8

 this is the location of point Q

Joe said that the absolute values of the numbers represented by the two points are the same.

What value of c makes the trinomial below a perfect square x2 + 7x + c?
Daniel [21]
We have that
x²<span> + 7x + c
</span><span>Group terms that contain the same variable
</span>(x² + 7x )+ c
<span>Complete the square. Remember to balance the equation 
</span>(x² + 7x+3.5² )+ c-3.5²

Rewrite as perfect squares

(x+3.5)²+ c-3.5²
so
c-3.5² must be zero
c-3.5²=0------- c=3.5²------> c=12.25

the answer is
the value of c must be 12.25
