Answer:
Step-by-step explanation:
4(8+2n) = 4 + 4n
32 + 8n = 4+4n
4n = -28
n = -7
Answer:
It is a square.
Step-by-step explanation:
If you look at the space of the lines from point to point, it's a even amount of little squares, so therefore, it is a square.
Step-by-step explanation:
m = -91.3
Since you move from 91.3 to the other side of the equal sign, it becomes a negative number (-91.3)
Think of the equal sign as a seperator from the positive and negative side.
If you also get an equation like -x=91.3, just flip the -x, to x, and change the 91.3 to a negative 91.3!
Cheers!

The rise from the ground by the skateboard is 5.5 inches
<h3>How to determine the height above the ground?</h3>
The length of the skateboard is given as:
Length (l) = 18 inches
The angle of elevation (x) is
x = 17∘
Represent the height with h.
The value of h is calculated using the following tangent ratio:
tan(x) = h/l
Make h the subject
h = l * tan(x)
Substitute known values
h = 18 * tan(17)
Evaluate
h = 5.5
Hence, the rise from the ground by the skateboard is 5.5 inches
