Answer:
15
Step-by-step explanation:
Let's solve your equation step-by-step.
15+8x=45+6x
Step 1: Simplify both sides of the equation.
8x+15=6x+45
Step 2: Subtract 6x from both sides.
8x+15−6x=6x+45−6x
2x+15=45
Step 3: Subtract 15 from both sides.
2x+15−15=45−15
2x=30
Step 4: Divide both sides by 2.
2x
2
=
30

x=15
Answer:
x=15
Answer: 4
<u>Step-by-step explanation:</u>
f(x) = 4x³ - x² + 1 g(x) = x - 1
g(2) = (2) - 1
= 1
f(1) = 4(1)³ - (1)² + 1
= 4 - 1 + 1

I dont know sorry but im sure sonmeone else can help you im reallu sorry
Answer:

cosec(2t)=1/sin(2t) ==> 1/(2×cos(t)×sin(t))
cos(2t)= 1-2sin²t
or 2cos²t-1
or cos²t - sin²t
after we knew this informations we have to write it in the question
1/2×sint×cost-1/1/2×sint×cost=cos2t
-2×sint×cost+1/2sint×cost/1/2sint×cost=cos2t
the 2sint×cost will gone
-2×sint×cost+1=cos2t
lets take cos2t =1-2sin²t
-2×sint×cost+1=1-2sin²t
-2sint×cost=-2sin²t
cost=sint
that means the t is equal to 45 because sin45 and cos45 equal to √2/2
hopefully i didn't waste your time by reading and not understanding my English is not that good sorry
