12/2=6.
6X0.5=3
so the scale drawing is 3 inches long
10/2=5
5X0.5=2.5
so the width of the scale drawing is 2.5 inches
3+3+2.5+2.5=11
1.y=-7x-2
2.y=-4x+10
next time juust plug the numberes in for example for the first one right the y=mx+b then plug in 5 for the y and -1 for the x then -7 for the m then solve
Answer:
you are a square
Step-by-step explanation:
it says " i have 2 pairs of parallel sides and 4 right angles", and typically 4 right angles make a square
Answer:
