X^2+4x+4+12x+24-14=0
x^2+16x+14=0
x= -16 ± √(16)^2-4(1)(14) /2(1)
=-16± √200 /2
-16 ± 2√50 /2
-16 ± 10√2 /2

<em><u>Answer:</u></em>
4 or 7 (Check the explanation to see which one your equation <em>actually</em> is.
<em><u>Step-by-step explanation:</u></em>
One thing I want to clarify for you, It's Evaluate, not Avaluate.
Okay so, we want to find the value of 2^3x-1 and we know x = 1.
You didn't really clarify if the expression was
or
, so I'll be doing both:
For
, we should plug in x to get
and then simplify to get
.
2 to the power of 2 or
is equal to 2 * 2 or 4.
The second one,
, we should plug in x to get
and then to become
. 2 to the power of 3 or
is 8 and then minus 1 is 7.
20) 13=2f+5
2f=8
f=4
6x<=3
x<=1/2
-f-5(2f-3)=-f-10f+15=-11f+15
answer B
45+0,15*45=45+6,75=51,75$
Answer:
x=1000 or 10 to the 3rd power
