ANSWER
EXPLANATION
The given expression is
We remove the perfect squares under the radical sign.
We can now take square root of the perfect squares and simplify them further.
This simplifies to:
This further simplifies to:
Answer:
13 yds * 32 yds
Step-by-step explanation:
A=area, l=length, w=width
A=w*l
l=6+2w
A=w*(6+2w)
A=6w+2w^2
416=6w+2w^2
416/2=(6w+2w^2)/2
208=3w+w^2
208-208=3w+w^2-208
w^2+3w-208=0
w^2+16w-13w-208=0
w(w+16)-13(w+16)=0
(w-13)(w+16)=0 ==> w+16=0 ==> w=-16, w can't be negative.
w-13=0
<u>w=13</u>
l=6+2w
l=6+2(13)
l=6+26
<u>l=32</u>
Dimensions: 13 * 32
Multiply the length and width for a rectangle like the one shown.
5.3(2.6) = 13.78 square yards.
