Answer:
x = 11.7
Step-by-step explanation:
3(x + 3) = 4(4 + 7) => intersecting secant theorem
3(x + 3) = 4(11)
3x + 9 = 44
3x + 9 - 9 = 44 - 9
3x = 35
x = 11.7

Answer:
x = -
Step-by-step explanation:
Given
9x² + 30x + 25 = 0 ← left side is a perfect square
(3x + 5)² = 0, thus
3x + 5 = 0 ⇒ 3x = - 5 ⇒ x = -
solution is x = - with multiplicity 2
