Answer:
180
Step-by-step explanation:
why does it have to be 20 character long
Move the -2x^2 over to the other side to make it positive and then rewrite in descending order of x's. Like this: 2x^2 - 12X + 18. Factor out a 2 to make things easier: 2(x^2 - 6x + 9). Now factor what's inside the parenthesis. Both signs are the same and they're both negative: (x - )(x - ). It's up to us now to find out what goes inside there with those x's. What adds up to -6 has to multiply to +9. Two 3's fit inside there perfectly: -3-3=-6, and -3*-3=9, so the factors are (x-3)(x-3), and setting those equal to zero according to the Zero Product Property, x-3=0 so x = 3 with a multiplicity of 2.
Answer:
r ÷(-8) = 5
i have answered the question u asked earlier
Answer:
x ≈ 61.8
Step-by-step explanation:
Using the sine ratio in the right triangle
sin15° =
=
( multiply both sides by x )
x × sin15° = 16 ( divide both sides by sin15° )
x =
≈ 61.8 ( to the nearest tenth )
