824 just add all the sides so 12+12+400+400=824 and in simpler form w2+l2
Answer:
y=15
Step-by-step explanation:
y-7=8
Add 7 to each side to cancel out the 7 next to the variable.
You get y=15.
<u>Use the previous given coordinates to solve for B.
Y=mx+b,
(3)=1/6(12)+b
3= 2+b
3-2=b
1=b
</u>
84= 7(6+a)
84= 42 +7a
84-42= 42-42 +7a
42= 7a
42/7= 7a/7
6= a
-84= -6( p+6)
-84= -6p -36
-84+36= -6p -36+36
-48= -6p
-48/-6= -6p/-6
8 =p
