the answer is A. it is asking for the incorrect answer therefor all are correct except A.
P=w+l
42=(3x+7)+(2x-1)
42=5x+6
36=5x
x=36/5
plug in x
w=3(36/5)+7
w=28.6
l=2(36/5)-1
l=13.4
Answer:
5677
Step-by-step explanation:
2100 +1477 = 3577
2100+3577= 5677
Answer:
x = 7
Step-by-step explanation:
Because:
GD = x + 4
GC = 4x + 5
And D is the centroid of ABC
So GC = 3GD
<=> 4x + 5 = 3(x + 4)
<=> 4x + 5 = 3x + 12
<=> 4x - 3x = -5 + 12
<=> x = 7
Done!!
You ok?? :))
<span>The area of a square is (length of side)^2 , the perimeter of a square is 4*(length of side)
Then your answer is 4 * sq rt (506.25 f`t^2) = 4 * 22.5 ft =
= 90 ft of fence</span><span>Source(s):</span>
