Answer:
Since we knew that the triangles are similar, we have:
19/38 = (x + 7)/(3x + 3)
=> 1/2 = (x + 7)/(3x + 3)
=> 3x + 3 = (x + 7) . 2
=> 3x + 3 = 2x + 14
=> 3x - 2x = 14 - 3
=> x = 11
Answer:
x2 +2x−xy when x = 250 and y = −120 ... sic Algebra: Patterns and Equations (13:18)
Step-by-step explanation:
Intercept ⇒ when f(x) = 0
f(x) = 3x² - 12x - 1
3x² - 12x - 1 = 0
Answer: The two x-intercepts are (4.08, 0) and (-0.08, 0)
