Answer:
negative
Step-by-step explanation:
For perimeter you will add each side together so
8ft+22ft+12ft+16ft=58
So your perimeter is 58ft.
For area your going to divide the shape into 2 to get the area as this is an irregular shape, so
Base 1+base2x height / by 2
22+8 x4/2
30x4/2
120/2
60
If you’re wondering how I got 4 I subtracted 16 with 12 to know what the height was. Good luck!!
Answer: 7
Step-by-step explanation:
For L to be parallel to M, ( 7x + 9 ) must be equal to ( 8x + 2 ) because the two angles are corresponding to each other.
Equate both equation. That is,
7x + 9 = 8x + 2
Collect the like terms
7x - 8x = 2 - 9
- x = - 7
The minus sign will cancel out
X = 7
Therefore, the value of x that will make L||M is 7
