Solve using perfect square factoring patterns. y2 + 14y + 49 = 0

1 answer:

4 0

Y² + 14y + 49 = 0

We know a² + 2ab + b² = (a + b)²
(y)² + 2 x 7 x y + (7)² = 0
(y + 7)² = 0
y = -7

y = -7

Use the relationship between the angles in the figure to answer the question.

Brut [27]

Answer:

x + 49 + 28 = 180

Step-by-step explanation:

The angles on a straight line with x° are 28° and 49° respectively, side by side with x°. This is because, vertical angles are equal. Therefore, the angle vertically opposite 28° and 49° are equal to 28° and 49° respectively.

Therefore, since angles on a straight line is 180°, thus:

x + 49 + 28 = 180
