Just add the 11 to the other side since it’s negative, which gives you x=30
Answer:
(a) 320 cm²
(b) 75 cm³
Step-by-step explanation:
The scale factor from A to B is 8/4 = 2.
The scale factor of the areas is 2² = 4.
The scale factor of the volumes is 2³ = 8.
(a)
80 cm² * 4 = 320 cm²
(b)
600 cm / 8 = 75 cm³
It would be (x,y) = (-y,x). Rotating a figure 270 degrees clockwise is the same as rotating a figure 90 degrees counterclockwise. Hope this helps! :D Feel free to ask more questions.
