Answer:

- The graphed is attached.

- It's an enlargement.

Step-by-step explanation:

It is important to remember that a Dilation is defined as  a transformation in which the image and the pre-image have the same shape, but their sizes are different.

When the scale factor is greater than 1, the image obtained after the  dilation is greater than the pre-image and it is an "Enlargement".

When the scale factor is is between 0 and 1,  the image obtained after the  dilation is smaller than the pre-image and it is an "Reduction".

In this case we know that the scale factor is 4.

Since:

4>1

It is an Enlargement.

Now we need to multiply the coordinates of the vertices of VWXY by 4, in order to find the coordinates of the vertices of  V'W'X'Y'. Then:

V'=(-1*4,-1*4)=(-4,-4)\\\\W'(-1*4,2*4)=(-4,8)\\\\X'(2*4,-1*4)=(8,-4)\\\\Y'=(2*4,2*4)=(8,8)

Finally, we must draw the pre-image and the pre-image and label them, as you see in the picture attached.

Since <em>l</em> and <em>m</em> are parallel, the unlabeled angle adjacent to the 63° one also has measure (7<em>x</em> - 31)° (it's a pair of alternating interior angles).

Then the three angles nearest line <em>m</em> are supplementary so that

(7<em>x</em> - 31)° + 63° + (5<em>x</em> - 8)° = 180°

Solve for <em>x</em> :

(7<em>x</em> - 31) + 63 + (5<em>x</em> - 8) = 180

12<em>x</em> + 24 = 180

12<em>x</em> = 156

<em>x</em> = 13

The bottom-most angle labeled with measure (4<em>y</em> + 27)° is supplementary to the angle directly adjacent to it, so this unlabeled angle has measure 180° - (4<em>y</em> + 27)° = (153 - 4<em>y</em>)°. The interior angles of any triangle have measures that sum to 180°, so we have

(7<em>x</em> - 31)° + 63° + (153 - 4<em>y</em>)° = 180°

We know that <em>x</em> = 13, so 7<em>x</em> - 31 = 60. Then this simplifies to

123° + (153 - 4<em>y</em>)° = 180°

Solve for <em>y</em> :

123 + (153 - 4<em>y</em>) = 180

276 - 4<em>y</em> = 180

96 = 4<em>y</em>

<em>y</em> = 24

Please answer correctly math problemo

Answer:

38

Step-by-step explanation:

We have to substitute x with 2 and y with 4

when the sign of a operation is not expressed it means that the operation is a

multiplication

So we have

3*2 + 2*(4)^2

6 + 2*(16)

6 + 32
