Answer: 6(x-2)
Step-by-step explanation:
(x·2-8)-(2x·2+4)
(2(x-4))+2x·2-4
2(x-4)+2x·2-4
2(x-4)+4x-4
2(x-4+2x-2)
2(3x-4-2)
2(3x-6)
2·3(x-2)
6(x-2)
Answer:
the answer is 3(t+2)
Step-by-step explanation:
Answer:
6n + 12 =40
Step-by-step explanation:
You need to divide 12 by 16 to get a decimal that you can turn into a percent. 12 ÷ 16 = .75. You turn that .75 into 75%. Greg's football team won 75% of their games.
sec(2<em>x</em>) - 4 = 0
sec(2<em>x</em>) = 4
1 / cos(2<em>x</em>) = 4
cos(2<em>x</em>) = 1/4
2<em>x</em> = cos⁻¹(1/4) + 2<em>nπ</em> or 2<em>x</em> = -cos⁻¹(1/4) + 2<em>nπ</em>
(where <em>n</em> is any integer)
<em>x</em> = 1/2 cos⁻¹(1/4) + <em>nπ</em> or <em>x</em> = -1/2 cos⁻¹(1/4) + <em>nπ</em>
The first two positive solutions occur for <em>n</em> = 0 in the first family of solutions, and for <em>n</em> = 1 in the second family, so
<em>x</em> = 1/2 cos⁻¹(1/4) or <em>x</em> = <em>π</em> - 1/2 cos⁻¹(1/4)
<em>x</em> ≈ 0.659 or <em>x</em> ≈ 2.483
