Answer: 6=5 sorry if i am wrong
Step-by-step explanation:
X² + 2x +3
If the discriminent Δ = b²-4.a.c <0 , that means the roots (or the zero value) are nit REAL Number (they are imaginary or complex)
Δ = 2² - 4(1)3) = 4 - 12 = -8
since Δ = - 8 < 0 there are no real roots
Let’s condense the original expression and see if that’s one of the answers
-1/2(-3/2 x + 6x + 1) - 3x
First we distribute the -1/2
((-1/2)(-3/2 x) + (-1/2)(6x) + (-1/2)(1)) -3x
3/4x - 3x - 1/2 -3x
Combine like terms
(3/4 x - 3x - 3x) -1/2
-21/4 x - 1/2
We could make this a mixed number
-5 1/4 x - 1/2
(Mixed number: 5 times 4 plus one gets the numerator)
So the answer is D
The correct choices based on the Segment Addition Postulate are <u>C. WX + XY + YZ = WZ</u> and <u>E. WY + YZ = WZ</u>.
<h3>What is a segment addition postulate?</h3>
A segment addition postulate is a part of a segment line that consists of two endpoints and all of the points between them.
For example, the segment addition postulate of line segment, AC will be defined as the sum of the lengths of the segments, AB and BC being equal to the total length AC.

The possible addition postulates that can be created from WZ are:
WZ = WX + XY + YZ
WZ = WY + YZ
WZ = WX + XZ
Thus, the correct choices of the segment addition postulate are <u>Options C and E</u>.

Answer:
12 in
Step-by-step explanation:
r = 2.5 in
V = 235.5 in³
Find h
Use V = πr²h
so 235.5 = 3.14 * 2.5² * h
235.5 = 19.625 h
h = 235.5/19.625 = 12 in
