Answer:
x=2.600
Step-by-step explanation:
2x(x+4)+7+=(x+8)+ 2x(x+1)+12
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
-> 2*x*(x+4)+7+-((x+8)+2*x*(x+1)+12)=0
-> ((2x•(x+4))+7)-(((x+8)+2x•(x+1))+12) = 0
-> (2x • (x + 4) + 7) - (2x2 + 3x + 20) = 0
-> 5x - 13 = 0
-> Add 13 to both sides of the equation :
5x = 13
Divide both sides of the equation by 5:
x = 13/5 = 2.600

Answer:
x ≈ 12.96
Step-by-step explanation:
Using Pythagoras' identity in the right triangle
x² + 11² = 17²
x² + 121 = 289 ( subtract 121 from both sides )
x² = 168 ( take the square root of both sides )
x =
≈ 12.96 ( to the nearest hundredth )
