Step-by-step explanation:
x^2=9/49
√x^2=√9/49
x=+or-3/7
Answer:
What is the question?
Step-by-step explanation:
I dont see the question.
Area of paralellogram=legnth times height
l=legnth
h=height
area=96
lh=96
h is 4 less than l
h=-4+l
sub
l(-4+l)=96
-4l+l^2=96
minus 96 both sides
l^2-4l-96=0
factor
(l-12)(x+8)=0
set to zero
l-12=0
l=12
l+8=0
l=-8, imossible, legnth cannot be negative, disreagard this soultion
legnth=12cm
Answer:
80 or 40 linear feet
Step-by-step explanation:
So the total amount of units for sides is 6. (2 2 1 1)
240 ÷ 6 = 40
So if the river was on the long side it would be 80feet, if the river was on the short side it would be 40feet
