You are being asked to compare various expressions to the given one, and to determine which are equivalent and which are not. You are asked to simplify the given expression—collect terms.

The given expression ...

... 4y -8x² -5 +14x² +y -1

can be simplified by identifying like terms and adding their coefficients.

... y(4 +1) +x²(-8 +14) +(-5 -1)

... = 5y +6x² -6 . . . . . simplified form

Any expression that has a different y-term, a different x² term, or a different constant term is <em>not equivalent</em>.

Once you have found this simplified expression, you can drag it to the appropriate box. Looking at the top three expressions on the left, you see immediately that they have different y-terms, so all those go to the "not equivalent" box. The expression on the bottom row has a different x² term, so it, too, is "not equivalent". (The sign is negative instead of positive. Details matter.)

The remaining expression, the one on the far right, has the appropriate y-term and constant term. The x² terms have not been combined, so it is equivalent, but not fully simplified.

Mathematics what is the distance between A (-6 -3) and b (-14 -18)
eduard

Answer:

The answer is

<h2>17 units</h2>

Step-by-step explanation:

The distance between two points can be found by using the formula

d =  \sqrt{ ({x_1 - x_2})^{2} +  ({y_1 - y_2})^{2}  } \\

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

A (-6 -3) and b (-14 -18)

The distance between them is

|AB|  =  \sqrt{ ({ - 6 + 14})^{2}  +  ({ - 3 + 18})^{2} }  \\  =  \sqrt{ {8}^{2}  +  {15}^{2} }  \\  =  \sqrt{64 + 225}  \\  =  \sqrt{289}  \\  = 17 \:  \:  \:  \:  \:  \:

We have the final answer as

<h3>17 units</h3>

Hope this helps you

Please explain.
LekaFEV [45]

Answer:

25% probability

Step-by-step explanation:

If there are three questions with four possible choices, there are twelve total answer choices. if you only get one answer as the correct one in each question then there's three out of the twelve answer choices that are correct in total. Basically, 3/12 = .25 = 25%. that's for total.

Also, with each question having 4 answers with 1 correct, 1/4 = .25 = 25% as well.

I hope this helped!
