Answer:
B x=3
Step-by-step explanation:
12x = 2x^2 +18
Divide by 2
12x/2 = 2x^2/2 +18/2
6x = x^2 +9
Subtract 6x from each side
6x-6x = x^2 -6x+9
0= x^2 -6x+9
Factor
What 2 numbers multiply to 9 and adds to -6
-3*-3 = 0
-3+-3 =-6
0= (x-3) (x-3)
Using the zero product property
x-3 =0 x-3 =0
x=3 x=3
Mhm, absolutely. Notice that we do not have a common unit circle value for any division of 8. But we do have a value for is 7pi/4. Now in order to actually get the value of 7pi/8, we use a half angle formula. So what we do is we will write out the formula and plug 7pi/4 into that formula, this will give us the value of 7pi/8. So the formula we need to plug 7pi/4 into is this:
<span>±<span><span><span>1+cos2θ</span>2</span><span>−−−−−−−−−</span>√</span></span><span>SO if you plug in 7pi/4 for theta in that formula, you think you could simplify it to find 7pi/8?</span>
