NemiM [27]3 years ago

Given: f(x) = x² + 2x - 2
Add 2 to both sides: f(x) + 2 = x² + 2x
Complete the square: f(x) + 2 + (1) = x² + 2x + (1) → f(x) + 3 = (x + 1)²
Subtract 3 from both sides: f(x) = (x + 1)² - 3

Answer: B

HELP PLEASE!! ASAP <br> If triangles ABC and DEF are similar, what is y? Show your work.
Ivenika [448]

Answer:

y = 18

Step-by-step explanation:

Since the triangles are similar, the corresponding sides are in proportion, that is

\frac{BC}{EF} = \frac{AC}{DF} , substitute values

\frac{y}{12} = \frac{21}{14} ( cross- multiply )

14y = 252 ( divide both sides by 14 )

y = 18
