You need to find the scale by taking the same side of each polygon. I marked which sides you should take from each example. Scale factor is defined as the proportion of the one side to another. In our case: smaller side/ bigger side 1) scale factor k=9/12=3/4, which means that smaller figure is a 1/4 fourth smaller than the bigger one 2) k = 12/15= 4/5, which means that smaller figure is one fifth smaller than the bigger one 3) k =10/25= 2/5, so the bigger figure is 3/5 smaller from the bigger one 4) k= 8/16, which means that the smaller figure is a half of the bigger one
Answer: 1. I forgot how you write it but it adds 1/3 of the number, so for example 9/3 is 3, so you add 3 to 9 = 12 and then 21/3 is 7 and so you add 7 to 21 = 28. I forgot how you would write this but I know the answer is not 1/3 though because then that would be dilating. (srry this one isn't clear)
Also sorry I couldn't really help more I'm not very good at this stuff.

Answer: $50
Step-by-step explanation:
30 × 10 = 40 ft² [garden area]
40 ÷ 25 = 1.6
1.6 ≈ 2
For the area of the entire garden, you need to buy two bottles of fertilizer.
25 × 2 = 50 [fertilization cost for the whole garden]
I used my calculator and got x=1 y=3
solve for y to put them in your calculator
2.1x+4.2y=14.7
y = (14.7 -2.1x)/4.2
−5.7x−1.9y=−11.4
y=(-11.4 +5.7x)/(-1.9)
then using the ploting tool I plotted them and found where they intersected
