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:
No nail for youuuuuuu
Step-by-step explanation:
Answer:
A
Step-by-step explanation:
y = 180 - 100 - 38 (angle sum of triangle is 180 degrees)
= 42 degrees
x = 38 degrees (alternate angles on || lines)
z = 100 degrees (opposite angles on parallelogram are equal)
