Both diameter and height are scaled by 2.5.
Area is measured in squared units ( square centimetres).
Square the scale factor:
2.5^2 = 6.25
Multiply the area of the smaller vase by the scale:
2826 x 6.25 = 17,662.5 square cm.
You plug in the values so it would be 24=15k. Divide by 15 on both sides so k=24/15=1.6. :)

7:3
210:x
ask yourself what number is needed to multiply by 7 to get 210 ( so you'd divide 210 by 7 which is 30). Multiply the other side by thirty as well to get the value of x
3*30 which is 90
Answer:
7
Step-by-step explanation:
(-1^2)x 3 = 3
-1 x 4 = -4
