Step-by-step explanation:
Expand ![\bold{2\left(1+2x\right): \ 2+4x}](https://tex.z-dn.net/?f=%5Cbold%7B2%5Cleft%281%2B2x%5Cright%29%3A%20%5C%202%2B4x%7D)
![\bold{3+4x](https://tex.z-dn.net/?f=%5Cbold%7B3%2B4x%3C2%2B4x%7D)
Subtract 3 from both sides
![\bold{3+4x-3](https://tex.z-dn.net/?f=%5Cbold%7B3%2B4x-3%3C2%2B4x-3%7D)
Simplify
![4x](https://tex.z-dn.net/?f=4x%3C4x-1)
Subtract 4x from both sides
![\bold{4x-4x](https://tex.z-dn.net/?f=%5Cbold%7B4x-4x%3C4x-1-4x%7D)
Simplify

Answer:
angle 7= 66
Step-by-step explanation:
Angle 1 is equal to the 114 degrees. And angle 1 + angle 7 = 180. So it would be 114 + angle 7 = 180. So you do 180-114 = 66. So angle 7= 66.
The other way is that 114 + angle 6 = 180, so you do 180-114= 66.
And agle 6 is equal to angle 7, so that's another way you can know that angle 7= 66
I don't think this is math, sorry, lol
X^2 - 16x + 56 = 0
= (x - 8)^2 - 64 +56= 0
= (x - 8)^2 - 8 = 0
x^2 - 8x + 11 = 0
(x - 4)^2 - 16 + 11
(x - 4)^2 - 5 = 0
(x + 15)(x + 5) = 96
x^2 + 20x + 75 = 96
(x + 10)^2 - 100 + 75 = 96
(x + 10)^2 = 96 +25 = 121
taking square roots:-
x + 10 = 11
x = 1
