Answer:
x < 1 and x > -19
Step-by-step explanation:
(4 |x+9|)/5<8
4 |x+9| < 40
|x+9| < 40/4
|x+9| < 10
x + 9 < 10. x < 1. (Positive answer: <)
x + 9 > - 10. x > - 19 (negative answer: >)

Step-by-step explanation:
Easy:
formula for parallelogram is b times h
so 5 times 14 =
70 sq mm.
-3+3r = 12
3r = 12+3
3r = 15
r = 5
Answer for the first one - it's complicated, but that maths is correct
I kind of cheated and did it a different way than they'd expect. By doing 24 squared, that gives you 576.
since both angles are 45 degrees, then the sides are equal lengths. Therefore x squared times 2 = 576.
Because of this, x squared = 576 divided by 2, which equals 288.
Therefore the square root of 288 = 12 square root 2
