a perfect square trinomial, (x + y)² = x² + 2xy + y²
so, if we have the x of the bx, what is left is the b
the expression would have to be (x + 7)², since we have the 49 and the x²
so, what's left: x² + 14x + 49,
b = 14

Answer:
Step-by-step explanation:
z = 4, z = 12
Absolute value does not take into account negatives. After the equation is done the sign switches if negative
|4 - 8| = |-4| = 4
|12 - 8| = |4| = 4
Answer:
The measure of the he angle A is 360°
