Answer:

x = -14

)Step-by-step explanation:

To find the value of x

Transpose

4(x + 2) = 3 (x - 2)

4x + 8 = 3x - 6

4x - 3x = -6 -8

x = -14

we can even cross check

<em>putting the value of x by -14</em>

4(x + 2) = 3 (x - 2)

4 (-14 +2) = 3 (-14 -2)

-56 +8 = -42 -6

-48 = -48

same = same

so CROSS-CHECKED

Answer:

Hello,

Step-by-step explanation:

y-intercept: x=0 ,f(0)=-10

$x^3-8x^2+17x-10\\\\=x^3-5x^2-3x^2+15x+2x-10\\\\=x^2(x-5)-3x(x-5)+2(x-5)\\\\=(x-5)(x^2-3x+2)\\\\=(x-5)(x^2-x-2x+2)\\\\=(x-5)(x(x-1)-2(x-1))\\\\=(x-5)(x-1)(x-2)\\$

x-intercepts are: 5,1,2.

Math geometry show work Thanks

Problem 1, part (a)

<h3>Answer: False</h3>

For instance, 200 feet in real life can be reduced to scale down to say 2 inches on paper. So we have a reduction going on, and not an enlargement.

====================================================

Problem 1, part (b)

<h3>Answer: true</h3>

This is because a scale drawing involves similar polygons. This is true whenever any dilation is applied.

====================================================

Problem 2

I'm not sure how your teacher wanted you to answer this question. S/he didn't give you any numbers for the side lengths of the polygon. The angle measures are missing as well.
