20/49.99
≈ 40%
Because you're taking 20 out of 49.99.
Answer:
7(b^2 -2)(b^2 +2)
Step-by-step explanation:
Factoring the common factor 7 from both terms, you get the difference of squares. That can also be factored.
v = 7(b^4 -4) = 7(b^2 -2)(b^2 +2)
The difference b^2-2 will have irrational factors, so does not meet the problem requirements. This is the factorization over integers.
13) 9 over 4 × 4 over 3
9 × 4 over 4 × 3
36 over 12 = 3 over 1
Therefore, your answer would be 3 over 1
14) 7 over 5 × 20 over 9
7 × 20 over 5 × 9
140 over 45 = 3 and 1 over 9
Therefore, your answer would have to be: 3 and 1 over 9.
