2: \sqrt21 - 2\sqrt(7)
3: 4\sqrt3 - \sqrt15
4: 2\sqrt5 - \sqrt10
5: -3 + 3\sqrt5
I already gave you these answers man
Step-by-step explanation:
We have ( 5x+16 + 8x + 4 - 4x -2 )/3 = (9x + 18) / 3 = 9( x + 2 ) / 3 = 3( x + 2 ) = 3x + 6;
The value of the scale factor k, is 1.5
<h3>
Perimeter</h3>
The perimeter of a shape is the sum of the side lengths of the shape
<h3>
Dimensions </h3>
The dimensions of the triangle MNO are given as:



Calculate the perimeter of the triangle as follows:


Divide 17.25 by 11.5 to calculate the scale factor (k)


Hence, the scale factor is 1.5
