The GCF is 5b.
10ab + 15b = 5b (2a + 3)
15b+2-13 = 13b+6-4b 15b-11 = 9b+6 15b-9b = 6+11 6b = 17 b =17/6 or 2 and 5/6
15b/39b4 = 5/13*b-3

The GCF is 5b.
3(2b2 - 5b - 2)
ex: 2x2 + 6bx + 5x + 15b Group 1st 2 terms and last 2 terms. Factor separately. = (2x2 + 6bx) + (5x + 15b) Factor using gcf = 2x(x + 3b) + 5(x + 3b) notice the parenthesis are the same = (2x + 5)(x + 3b)
Re-ordering it : 13a - a -15b + 2b = 12a - 13b
10ab + 15b = 5b (2a + 3)
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
15b+2-13 = 13b+6-4b 15b-11 = 9b+6 15b-9b = 6+11 6b = 17 b =17/6 or 2 and 5/6
Assuming 15b means the lengths of each side of the square base and 12l means the length of the triangle from the top to the bottom (note that I'm not assuming 12l is the height of the pyramid) the SA (surface area) will be: 15^2 + 15x12x4/2 = 225 + 360 = 585 units squared (whatever your units are)
3 x 5 x b = 15b No exponents required.
15b/39b4 = 5/13*b-3
I can help with that. Would you like a translation of a specific sentence or section from ecce Romani 1 exercise 15b?
15b + 13c - 12b + 10c + 8 = 3b + 23c + 8
