10+10+10+10= 40
40+38+40+35+35= 188 total perimeter
The answer is (-1,-7) because you are pluging it in -1 is x and -7 is y. so 7×-1=-7 and 5×-7 = -35 so -7 minus -35 =28
Answer:
(7m + 63)/3x = k
Step-by-step explanation:
<em>m=3kx/7 - 9</em>
<u><em>add 9 to both sides:</em></u>
m+ 9 = 3kx/7
<u><em>multiply both sides by 7:</em></u>
7(m+9) = 3kx
<u><em>distribute the 7:</em></u>
7m+63 = 3kx
<u><em>divide both sides by 3x:</em></u>
<u>(7m + 63)/3x = k</u>
