Hello there!
Here is the answer worked out for you!
12x[-1+sqrt(5)]
-12x+12xsqrt(5)
Remember that you can only add like terms so you can't add -12x to 12xsqrt(5). The radical makes it an unlike term.
I hope this helped and best wishes!
Answer:
C. 0
Step-by-step explanation:
–4j^2 + 3j – 28 = 0
The discriminant is b^2-4ac if >0 we have 2 real solutions
=0 we have 1 real solutions
<0 we have 2 imaginary solutions
a = -4, b =3 c = -28
b^2 -4ac
(3)^2 - 4(-4)*(-28)
9 - 16(28)
9 -448
This will be negative so we have two imaginary solutions.
Therefore we have 0 real solutions
Remember these two combinations: logab=loga+logb, log(a/b)=loga-logb
3logx=logx^3
(1/2)log(x+2)=log(x+2)^(1/2)
2log(z-4)=log(z-4)^2
so the given expression can be combined into log{[(x^3)(z-4)^2]/(x+2)^(1/2)}
Answer:
5
Step-by-step explanation:

Here LCM will be 6. (We made the denominator same)
so, now the equation will be :
= 5/6
So, the value in the red box is 5.
Hope it helps!
Each book costs $34 for this problem you need to first subtract 18 from 324 which gets you 306 then divide 306 by 9 and you get 34
