Answer:
The length is <u>8</u> ft.
The width is <u>2</u> ft.
Step-by-step explanation:
A = l*w
l = w + 6
16 = w(w + 6)
16 = w^2 + 6w
w^2 + 6w - 16 = 0
(w + 8)(w - 2) = 0
w = -8ft or 2ft
Since lengths cannot be negative in reality, <u>w = 2ft</u>.
l*2 = 16
<u>l = 8ft</u>
Answer:
let X represent the number of spider.
8x+6*(x+1)=160
8x+6x+6=160
14x=154
x=11
x+1=11+1=12
So the number of ants is 12, the number of spiders is 11.
