Solve 3x^2 + 18x + 15 = 0 by completing the square.
a: 3(x + 3)^2 = 6; x = −3 + √2, x = −3 − √2
b: 3(x + 9)^2 = 12; x = −11, x = −7
c: 3(x + 3)^2 = 12; x = −5, x = −1
d: 3(x + 9)^2 = 228; x = −9 + √76, x = −9 − √76

my math:
3x^2 + 18x + 15 = 0
3(x^2 + 18x + ) + 15 = 0
3(x^2 + 18x + 81) + 15 - 81 = 0
(x^2 + 18x + 81) - 228 = 0

what do i do now? can someone me ?

image result for what is another name for consecutive interior angles? ​

when two lines are crossed by another line (called the transversal): the pairs of angles on one side of the transversal but inside the two lines are called consecutive interior angles. in this example, these are consecutive interior angles: d and f.

step-by-step explanation:

hello :

by applying the distributive property :

6 × 4.3 = 6 × ( 4 + 0.3 )

            =   (6 ×   4) + (6 ×   0.3)

            = 24 + 1.8

6 × 4.3 = 25.8
