URGENT!: Which best explains why these two figures are similar or not similar?
-BARSIC- [3]

Answer:

These two figures are similar because \frac{5}{3} equals \frac{15}{9}.

Step-by-step explanation:

The figures will be similar if their ratios of the two sides are equal. So we need to check the ratios of the figures to see if they are similar or not.

For the smaller figure the ratio is \frac{5}{3}, and for the bigger figure the ratio is \frac{15}{9}. which upon simplification reduces to  \frac{5}{3}.

So we see that the ratios are equal. Thus the figures are similar.

5-7k=-4(k+1)-3 add work pleasee!!!
marshall27 [118]

Answer:

k=4

Step-by-step explanation:

5-7k=-4(k+1)-3

Distribute

5-7k=-4k-4-3

Combine like terms

5-7k=-4k-7

Add 7k to each side

5-7k +7k = -4k+7k-7

5 = 3k-7

Add 7 to each side

5+7 = 3k-7+7

12 = 3k

Divide by 3

12/3 = 3k/3

4=k
