Area  = 1/2 h(b + B)
1/2.10.(b + 12) = 100
5(b + 12) = 100
b + 12 = 100 ÷ 5
b + 12 = 20
b = 20 - 12
b = 8

In 10 years, Roman will be 2 times Seth's age. 5 years ago Roman was 3 times Seth's age. HOW OLD IS SETH???
aalyn [17]
Let s be Seth's age. let r be Romans age. 5 years ago Seth was s-5 and Roman was three times as old, or 3(s-5), or 3s-15=r-5

in ten years Seth will be s+10 and Roman will be twice as old, or 2(s+10), or 2s+20=r+10
3s-15 =r-5
r=3s-10

2s+20=r+10
r=2s+10

3s-10=2s+10
s=20

Seth is 20 years old

setting the two equations equal gives us
3(s-5)=2(s+10)
3s-15=2s+20
s=35

80 points! Look at pic attached. I will mark brainiest if you explain your reasoning good. Random answers will be reported.

Answer: No, your friend is not correct. You cannot use a similarity transformation to turn a square into a rectangle. Here's why:

1) If you used a similarity transformation, the size and position of the shape would change, but the shape itself remains the same.

2) Squares and rectangles are NOT similar.* Referring to the first point I listed, if the shapes are not similar, then a similarity transformation cannot be used to turn one shape into another.

<em>*Similar means that the edges are proportional to one another, such as a square with sides of 4 meters vs a square with sides of 2 meters: the sides are different lengths, but the shape is the same.</em>

I hope this helps! Please feel free to comment below if you need any clarification. Have a good day, and good luck on your assignment. :)
