$\\ \sf\longmapsto 0.9(7x+14)=1.5-(x+2)$

$\\ \sf\longmapsto 6.3x+12.6=1.5-x-2$

$\\ \sf\longmapsto 63x+12.6=-x-0.5$

$\\ \sf\longmapsto 63x+x=-0.5-12.6$

$\\ \sf\longmapsto 64x=-13.1$

$\\ \sf\longmapsto x=\dfrac{-13.1}{64}$

$\\ \sf\longmapsto x=0.2$

Tristan is working on dilating rectangles. Rectangle ABCD is dilated by a factor of 3. The resulting rectangle WXYZ has an area

zloy xaker [14]

Answer:

Tristan is correct, because he needs to find the possible dimensions for rectangle WXYZ and then divide each dimension by 3.

Step-by-step explanation:

The rectangle ABCD is dilated by a factor of 3 to get the rectangle WXYZ whose area is found to be 72 cm².

Let the dimensions of the dilated rectangle WXYZ are a cm by b cm.

So, ab = 72 ........... (1)

Now, the dimensions of the original rectangle are 3 times lesser than the dimensions of rectangle WXYZ.

So, the area of rectangle ABCD will be $(\frac{a}{3} \times \frac{b}{3}) = \frac{ab}{9} = \frac{72}{9} = 8$ cm² {from equation (1)}

Therefore, Tristan is correct, because he needs to find the possible dimensions for rectangle WXYZ and then divide each dimension by 3. (Answer)
