Answer:
W=32
L=70
Step-by-step explanation:
L=2w+6
204=2L+2W
204=2w+2(2w+6)
204=2w+4w+12
192=6w
w=32
L=2(32)+6
L=70
Answer:
2x + 4y = 14 = x= −2y+7
3x - 4y = -39= x= 4=3
y−13

Answer:
I simply listed the factors of 24, and tested which ones worked in this equation: P = 2a + 2b.
So the factors listed were:
24 x 1
12 x 2
8 x 3
6 x 4
After testing each one of these, 6 and 4 had worked for me.
P = 2(6) + 2(4)
P = 12 + 8
P = 20
Therefore, the dimensions of this rectangle are 6 and 4.
