10ab + 15b = 5b (2a + 3)
The GCF is 5b. 5b squared is 25b or (5 x 5) x b 15b is (3 x 5) x b Therefore; 5 x b in each or 5b is GCF
The GCF is 5b.
(ab/b) / (4a/5b) =(ab / b) * (5b / 4a) = (5ab2 / 4ab)= 5 / (4b)
The GCF is 5b.
10ab + 15b = 5b (2a + 3)
The GCF is 5b. 5b squared is 25b or (5 x 5) x b 15b is (3 x 5) x b Therefore; 5 x b in each or 5b is GCF
The GCF is 5b.
3(2b2 - 5b - 2)

3(7a - 5b) + 2(4a - 3b) Multiply the contents of each bracket by the number outside it: 21a - 15b + 8a - 6b Bring like terms together: 21a + 8a - 15b - 6b Combine like terms: 29a - 21b This cannot be simplified further.
(ab/b) / (4a/5b) =(ab / b) * (5b / 4a) = (5ab2 / 4ab)= 5 / (4b)

-3-5b/7 = -4 Multiply all terms by 7: -21-5b = -28 Add 21 to both sides: -5b = -7 Divide both sides by -5 remembering that a -/- becomes a + Solution: y = 7/5 = 1.4
5b + 5b = 2 x 5b
The GCF is 5b.
2a+5b isn't possible the answer is still 2a+5b.
