5*12 is 60 
60+4 is 64
60 (final answer for a)
#10
n+3 divided by 8 = -4
8*(-4) =  -32
-32 + 3 = -35
 -32 (final answer for n)
#11
6+z divided by 10 = -2
-2 * 10 = -20
-20=6=-26

How many terms are in the polynomial abcd + e - h 2?<br><br> two
a_sh-v [17]

There are three terms in the polynomial.

Step-by-step explanation:

Given that,

A polynomial, abcd + e - h^ 2.

To find,

The number of terms in the polynomial.

Solution,

The number of terms in the polynomial are the number of unlike expressions that are separated by a minus or plus.

We have, abcd + e - h^ 2.

The terms are :

abcd, e,-h^2

It implies that there are three terms in the given polynomial.

How would you solve this problem?<br><br> ((2x^12y^3)/(x^10y))^-5
Hatshy [7]
There is no equals sign. Are we looking for x, or y?

Either way, with the -5 exponent outside the parentheses, you can multiply that to each exponent in the fraction to get rid of it.

I'm not sure what you mean by 2x^12y^3. Is it an exponent within another exponent?

A triangle is dilated by a scale factor of 1/5 and then rotated 90 degree clockwise about the origin. Why is the image similar t
yan [13]
<u><em>Answers:</em></u>
The corresponding angles of the triangles are congruent
The image is a reduction of the pre-image
Neither the dilation nor the rotation change the shape of the triangle

<u><em>Explanation:</em></u>
<u>For shapes to be similar:</u>
1- there should be a ratio between the sides
2- angles in first shape should be congruent to angles in second shape

Now, a scale factor of 0.2 means that the sides of the image are 0.2 of the length of the original shape. However, angles are not changes

<u>Let's check the choices:</u>
<u>1- </u><span><u>The corresponding sides of the triangles are congruent:</u>
This option is incorrect as dilation changes the lengths of the sides

<u>2- </u></span><span><u>The corresponding angles of the triangles are congruent:</u>
This option is correct as neither dilation nor rotation alters the measures of the angles

<u>3- </u></span><span><u>The corresponding sides of the image are 5 times as long as those of the pre-image:</u>
This option is incorrect as the sides of the image are only 0.2 times as long as those of the pre-image

<u>4- </u></span><span><u>The image is a reduction of the pre-image:</u>
This option is correct as the sides of the image are 0.2 times those of the pre-image which means that the shape is reduced

<u>5- </u></span><span><u>Neither the dilation nor the rotation change the shape of the triangle:</u>
This option is correct as both dilation and rotation are rigid transformations that do not alter the shape of the triangle (a triangle remains a triangle only with different side lengths)

<u>6- </u></span><u>The rotation reduces the size of the triangle:</u>
This option is incorrect as rotation does not alter the size of the shape. It only changes its position

Hope this helps :)
