Answer:
x=6
Step-by-step explanation:

You would multiply it by 4
4(3x^2 +2 )
12x^2 +8
I believe the answer is C
17
linear has 1 as highest exponent
D has x^2
D is not linear
18. find slope
(y2-y1)/(x2-x1)=(-1-2)/(0-4)=-3/-4=3/4
y=3/4x+b
B is answer
The expression that expresses all possible lengths of segment AB is 27 < AB < 81. The correct option is the second option 27 < AB < 81
<h3>Properties of a triangle</h3>
From the question, we are to determine the expression that expresses all possible lengths of segment AB
From one of the properties of a triangle,
The <u>third side</u> of any triangle is greater than the difference of the other <u>two sides</u>; and the <u>third side</u> of any triangle is lesser than the sum of the <u>two other sides</u>
Then, we can write that
AB < 27 + 54
and
AB > 54 - 27
Putting the two inequalities together, we get
54 - 27 < AB < 27 + 54
27 < AB < 81
Hence, the expression that expresses all possible lengths of segment AB is 27 < AB < 81. The correct option is the second option 27 < AB < 81
