Answer:
∠Y = 55°
Step-by-step explanation:
Since triangle ABC and XYZ are congruent, that means that...
∠A = ∠X
∠B = ∠Y
∠C = ∠Z
Since ∠Y = ∠B and ∠B = 55°, that means ∠Y = 55°.
Você pode, mas não receberá um bom número limpo. Eu recomendo que você faça divisão longa

Answer:
See below.
Step-by-step explanation:
f(x) = -|x + 9|
compared to
f(x) = |x|
has a graph that opens downward in an upside down V shape.
It has been moved 9 units left compared to the graph of f(x) = |x|.
It reflects over the x-axis.
Answer:
A
Step-by-step explanation:
2x² + 5x = 12
2x² + 5x - 12 = 0
x² + 5x - 24 = 0
factors of 24 are 1, 2, 3, 4, 6, 8, 12, 24. the only pair that adds to 5 is 8 and 3
2x² - 3x + 8x - 12 = 0
split the equation and factor
2x² - 3x = 0 ||| 8x - 12 = 0
x(2x - 3) ||| 4(2x - 3)
therefore the pair is (2x - 3)(x + 4)
2x - 3 = 0
2x = 3
x = 3/2
or
x + 4 = 0
x = -4
