Answer:

12∠x∠16

Step-by-step explanation:

For the triangle to be acute,a²+b²+c²,

Where c is the largest side of the triangle.  

Hence, we must say x²+(x+4)²≥20²,  

or after simplifying, x²+4x-192≥0 or (x+16)(x-12)≥0

Since x must have positive values only, x≥12

Therefore, for the triangle to be acute,we must have 12≤x≤16.

Figure b is a scale image of Figure A, as shown. Figure a is an Rectangle with 9 on left side and 12 on bottom of rectangle. and
Ronch [10]

The scale factor that was applied to figure A to produce figure B is: 11/3 = 3.67.

<h3>How to Find the Scale Factor of a Dilation?</h3>

The ratio of the corresponding dimensions of the image to the preimage gives the scale factor of any dilation.

That is:

Scale factor = dimension of image (new figure) / corresponding dimension of pre-image (original figure).

The scale factor that was applied to figure A to produce figure B = dimension of figure B / corresponding dimension of figure A.

A dimension of figure B = 33

Corresponding dimension of figure A = 9

Therefore, we would find the scale factor as shown below:

The scale factor that was applied to figure A to produce figure B = 33/9

= 11/3 = 3.67

Therefore, the scale factor that was applied to figure A to produce figure B is: 11/3 = 3.67.

Given the equation kx – 17 = 51 + x, where k=1, solve for X.
IgorC [24]

Answer:

  • No solution for x, when k = 1
  • x = 68/(k - 1), when k≠ 1

Step-by-step explanation:

<u>Given the equation</u>

  • kx – 17 = 51 + x, where k = 1,

<u>Solve for x:</u>

  • 1*x - 17 = 51 + x
  • x - 17 = x + 51
  • x - x = 51 + 17
  • 0 = 68,

Incorrect equation, no solution for x when k=1

<u>Solving for x when  k ≠ 1</u>

  • kx - 17 = 51 + x
  • kx - x = 51 + 17
  • x(k - 1) = 68
  • x = 68/(k - 1)
