Answer:
1-1) A=6×5=30m² | P=6×2+5×2=12+10=22m
1-2) A=5×20=100mi² | P=5×2+20×2=10+40=50mi
2-1) A=16×6=96m² | P=16×2+6×2=32+12=44m
2-2) A=20×9=180km² | P=20×2+9×2=40+18=58km
3-1) A=14×17=238yd² | P=14×2+17×2=28+34=62yd
3-2) A=20×18=360mi² | 20×2+18×2=40+36=76mi
Answer:
C
Step-by-step explanation:
Constant proportionality is measured by y. In this case it would be 25.
his average test score would be 82
you add together all the test scores
90 + 76 + 84 + 66 + 96 + 89 + 73 =574
and then you divide that number by how many scores there were
574 ÷ 7 = 82
-6 < x + 1 ≤ 1
<u>-1 -1 -1</u>
-7 < x ≤ 0
-7 < x or x ≤ 0
x > -7 or x ≤ 0
