Answer:
2. 7.2
3. (7,6)
4. (6,-7)
sorry but question no 1 i cant answer cause the pic is too blurry
A=LW, and we are told that L=W+10
Using L=W+10 in A=LW you have:
A=(W+10)W
A=W^2+10W
W^2+10W=880, we are told that A=880 so
W^2+10W=880 now we can complete the square...
W^2+10W+25=905
(W+5)^2=905
W+5=±√905
W=-5±√905, since W>0
W=-5+√905 and since L=W+10
L=5+√905
W=-5+√905 ft and L=5+√905 ft
If we want an approximation:
W≈25.08 ft and L≈35.08 ft (both dimensions to the nearest hundredth)
