Evaluate the expression.<br><br> - 4(2 - 5)2 + 82
Pavlova-9 [17]

Answer:

106

Step-by-step explanation:

Ok this question is a bit confusing but once you understand the concept you will be able to answer the question correctly

Always know that bracket is solved first once it is found in the question

So back to the question

-4(2-5)2+82

So let's get to work...

Bracket first

-4(-3)2+82

Multiply with the number at the front then followed by the one at the back

(+12)2+82

24+82

106

Therefore the final answer is 106

I believe you understand how we get the answer...just be careful when solving this kind of question... simple

If ac =x+3 and db=3x-19, find ac
AveGali [126]
We need some sort of diagram to see what they are. Is there any way to say that ac = db? Either equal angles or equal lines. 
x + 3 = 3x - 19 Add 19
x + 3 + 19 = 3x Subtract x
21 = 2x
x = 21 / 2
x = 10.5

ac = 10.5 + 3
x = 13.5

Explain how the segment addition postulate can be modeled using a real-world object
IgorC [24]

To determine the length of AB, one must subtract BC from AC. If the length of AC is 18 and the length of BC is 4, then using this formula yields 18 - 4 = 14, so the length of AB is 14.

This postulate also allows a line segment that has only two known points to be broken into two line segments with the addition of a third point in between the endpoints. This is useful for proofs in geometry and analysis.

Triangle MNO is rotated 180 using the origin as the center of rotation .Which sequence of transformations will produce the same
stiks02 [169]

180° rotation about the origin changes the signs of the coordinates.

(x, y) → (-x, -y)

It is a reflection over the y-axis and a reflection over the x-axis (in either order).

<em>You did not provide the options so hopefully you can figure out the answer based on the information I provided.</em>
