we have been asked to simplify
![(3x-5)-(5x + 1)](https://tex.z-dn.net/?f=%20%20%283x-5%29-%285x%20%2B%201%29%20)
To Simplify this, we will first open the parenthesis, as below
![(3x-5)-(5x + 1)=3x-5-5x-1\\ \\ \text{take the like terms together and simplify we get}\\ \\ (3x-5)-(5x + 1)=3x-5x-5-1\\ \\ (3x-5)-(5x + 1)=-2x-6\\ \\\\](https://tex.z-dn.net/?f=%20%283x-5%29-%285x%20%2B%201%29%3D3x-5-5x-1%5C%5C%20%5C%5C%20%5Ctext%7Btake%20the%20like%20terms%20together%20and%20simplify%20we%20get%7D%5C%5C%20%5C%5C%20%283x-5%29-%285x%20%2B%201%29%3D3x-5x-5-1%5C%5C%20%5C%5C%20%283x-5%29-%285x%20%2B%201%29%3D-2x-6%5C%5C%20%5C%5C%5C%5C%20)
Hence the simplified expression is -2x-6
Answer:16
w(u(2))
= - 2(2×2 - 1 )^2 - 2
= - 2(4 - 1 )^2 - 2
=-2(3)^2-2
=2×9-2
=18-2
=16
Data:
<span>segment AU = 20x + 108,
segment UB = 273,
segment BC = 703,
segment UV = 444,
segment AV = 372 and
segment AC = 589.
From the figure:
1) Similarity => segment AB / segment BC = segment AU / segment UV
2) segment AB = segment AU + segment UB = 20x + 108 + 273 = 20x + 381
=> (20x + 381) / 703 = (20x + 108) / 444
=> 444 (20x + 381) = 703 (20x + 108)
=> 8880x + 169164 = 14060x + 75924
=> 14060x - 8880x = 169164 - 75924
=> 5180 x = 93240
=> x = 93240 / 5180
=> x = 18
Answer: x = 18

Not sure for the rest but 9 and 11 should switch answers and 10 is square.
Hope this helps
