Similar triangles have corresponding sides with proportional lengths.
AB/BC = DE/EF
5/9 = 7.5/EF
5(EF) = 9 * 7.5
5(EF) = 67.5
EF = 13.5
When a shape's area is 9 times as great, the one dimension difference is √9=3 times as great. Therefore the length of all sides are 3 times of the corresponding sides of the original shape. The shortest side in the original shape is 3, the larger one is 3 times of that, which is 9. General rule, if a similar shape is x times ratio in terms of sides, the area will be x^2 times the original. <span>Hope it helps.</span>
Answer:
-1.5 > -32 / -45 > -54 / -35 > -610 / -23 < 13
Step-by-step explanation:
If you're looking at negative numbers, the smallest is that greatest because it's close to the 0. In a line, -2 --- -1 --- 0 --- 1 --- 2 , two is the greatest and negative two is the smallest just because it's a positive number.
