Answer:
The first one is 20, second is 5 3/5, the third one should be 22.8, fourth is 1, fifth is 15.9
Step-by-step explanation: Add all the numbers up (for each shape). For the parallelogram multiply the top and right sides by two.
The equation would be y = | x + 1 |.
According to property the diagonals are equal in rectangle
6x+19=9x-5
9x-6x=19+5
3x=24
x=24/3
x=8
Just add them
$3.50 + $8.75= $12.25
Hope this helps
