In the expression '15b + 23b + 10', the coefficients are 15, 23, and 10.If you simplify the expression to '38b + 10", then the coefficients are 38 and 10.
The terms in this question are like so you can simply add them together.15b2 + b2 = 16b2Let's just test this (let b = 2)!(15 * 22) + 22 = (15 * 4) + 4 = 6416 * 22 = 16 * 4 = 64
Divide 300 by 15 to get the answer. The answer is 300/15.
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.
