Answer:
72cm²
Step-by-step explanation:
perimeter= 2(l+w)
36 = 2(l+w)
36/2 = l+w
18 = l+w
since, l is twice as w
18= 2w + w
18 = 3w (we can add since all the variables, and exponents are same)
18/3 = w
6= w
NOW,
w=6 and l is equal to twice as 6
so l=12
area= l×b
= 12×6 = 72cm²
hope this helps. It was toooo long

Answer:
(x, y) = (-1, 1)
Step-by-step explanation:
8x + y = −7
for y = 1
8x + 1 = -7
subtract 1 from boh sides
8x = -8
divide bot sides by 8
x = -1
(x, y) = (-1, 1)
X+(x+1)+(x+2)+(x+3)=156
4x+6=156
4x=150
x=37.5 (not an integer)
If x=37 you get 37+38+39+40=154 and if x=38 you get 38+39+40+41=158[/tex]
