-9u + 3u = 9 + 9
-6u = 18
u = -18/6
u = -3
Thus, u is equal to -3
By the Pythagorean Theorem:
d^2=x^2+y^2
d^2=8^2+4^2
d^2=64+16
d^2=80
d=√80
d=4√5 ft
d≈8.944
So
A. No because the diagonal is close to 9 feet.
The reciprocal is 6/11. Hope this helps! :D
If f is a function and x is an element of its domain, then f(x) denotes the output of f corresponding to the input x. The graph of f is the graph of the equation y = f(x).
Formula for trapezoid area is A=b1+b2 x heightx 1/2 so your answer would be 161m squared
