Answer:
Yes
Step-by-step explanation:
4 x 3 = 12
5 x 3 = 15
12x5 is 60 is it suppose to be 12 times 5
Good job, you started on the right track, you just have to finish. You have to combine like terms(anything that's the same like x^3 and x^3, or like 8 and 2) (b): 2x^3+4x^2-9x+4 (d)6x^3-13x^2+11x+10 Hopefully that helps, and I'm sorry I'm bad at explaining
7cos(x) + 1 = 6sec(x)
7cos(x) + 1 = 6/cos(x)
7cos^(x) + cos(x) = 6
7cos^(x) + cos(x) - 6 = 0
[7cos(x) - 6][cos(x) + 1] = 0
cos(x) = 6/7 , x = arccos(6/7) and
cos(x) = -1, x = 180
