Answer: 6
Step-by-step explanation: since both triangles are similar, the sides are the same but different lengths. Because HI is 1 and HG and IG are 2, means that since YW is 5, that XY and XW would be equal to 6.
45 / 0.12 = 375
Answer: 375
Your answer is:
(125 - 8x^3) / (25 + 10x + 4x^2) = - ((2x - 5) * (4x^2 + 10x + 25)) / (4x^2 + 10x + 25) = - (2x - 5) = - 2x + 5
The correct result would be - 2x + 5.
X = 5 or x = 13.
