P = 2l + 2w
l = 2w
48 = 2(2w) + 2w
48 = 4w + 2w
48 = 6w
8 = w
l = 2w
l = 2(8)
l = 16
48 = 2(16) + 2(8)
48 = 32 + 16
48 = 48
Answer:
length = 16
width = 8
Answer:
6x+3
Step-by-step explanation:
(x+4)+(3x-2)+(2x+1)
=x+4+3x-2+2x+1
=x+4+3x-2+2x+1 --> Here I'm just bolding the variables. This makes it easier to combine like terms in the next line.
=6x+4-2+1
=6x+3
The second one should be the answer
