2.5 still if you make it a fraction it would be 2 and 1 1/2 so you can't simplify that any more
M[n(x)] = 4(x - 10) - 11 = 4x - 40 - 11 = 4x - 55
I think it is A)53 because the are the same size
Add <span>6</span> to both sides
<span>2x-6+6=4+6</span>
Simplify <span>4<span>+6</span></span> to <span>10</span>
<span>2x=10</span>
Divide both sides by <span>2</span>
<span>2x/2=10/2</span>
Simplify 10/2
<span><span>x=<span>5</span></span><span>

Answer:
steps below
Step-by-step explanation:
15 tan³x=5tanx .... (0,2π)
5tanx(3tan²x - 1) = 0
tanx = 0 <u>x = π</u> (0° is excluded)
or 3tan²x - 1 = 0
(√3 tanx + 1) (√3 tanx - 1) = 0
tanx = 1 /√3 <u>x = π/6 (30°) or x = 5π/6 (150°)</u>
tanx = - 1 /√3 <u>x = 7π/6 (210°) or x = 11π/6 (330°)</u>
