Answer:
Step-by-step explanation:
41 + 4x = 7x + 5(Exterior angle theorem)
36 = 3x
Hence x = 12
1.5 * 8/5 = 0.3*8 = 2.4
2.5 * 8/5 = 0.5*8 = 4.0
Solving equations simple
4n + 3 =11
Step-by-step explanation:
I think we have to find the factors so
3x2 + 42x + 105
First we will multiply 105 by 3 = 315 then find factors of 315 which may add or subtract = 42
So 45 and 7
3x2 + 45x - 7x + 105
3x( x + 15) - 7(x - 15)
(3x - 7) and ( x - 15) are the factors
