Answer:
D-159
Step-by-step explanation:
Answer:
or 6.75
Step-by-step explanation:
- To cancel out a fraction you multiply by the reciprocal. To make multiplying easier you can make -3 into a fraction by putting 1 under it
- Multiplying across, two negatives make a positive so the answer is positive

The perimeter is the measure around the shape, so just add all the sides together-
6+5x+x+2
6x+8
Since this is a right triangle, you multiply the legs (6 and x+2) and divide by 2
6(x+2)
6x+12
/2
3x+6
8. Is the answer! Hope this helps
