9x < -27 or 4x > 36
9 9 4 4
x < -3 x > 9
x ∈ (-∞, 3) or (9, ∞)
Answer:
x = - 3 / 2 ( in decimal form = - 1.5)
Step-by-step explanation:
9(x - 1) - 8x = -3(x + 5)
left side: 9(x - 1) - 8x
Expand... 9x - 9 - 8x
= (9x - 8x) - 9
= 1x - 9 or <em>x - 9</em>
right side: -3(x + 5)
Expand... <em>-3x - 15</em>
combine :
x - 9 = -3x - 15
Add 9 to both sides to get x alone
x - 9 + 9 = -3x - 15 + 9
x = -3x - 15 + 9
x = -3x - 6
Add 3x to both sides
x + 3x = -3x - 6 + 3x
simplified, 4x = -6
Now divided 4 from both sides
4x / 4 = -6 / 4
simplify, x = -6 / 4
You can reduce the fraction by dividing it by 2
(-6 / 2) / (4 / 2) = -3 / 2
Hope this helps, Let me know if you have any questions !
Have a nice day :)

1064.8 in^2
Step-by-step explanation:
12.1 x 17. 6 / 2 to find one half of a triangle will equal 106.48
there are 10 triangle therefore 106.48 x 10 = 1064.8
Answer:
A = 
. r^2
If A = 9ft^2
. r^2 = 9ft^2
r^2 = 9ft^2
r = sqrt(9ft^2)
r = 3ft ( r>0)
