Area= length*width
width=W
W*(3W-4)=615
3W^2-4W=615
3W^2-4W-615=0
W=41
W=-45
But W cant be a negative number so it is 41m (width)
The length is (41*3)-4=119m (length)
Area of a square = Side × Side
Side = 7x-3
Area of the square = (7x-3) × (7x-3)
= 7x(7x-3) -3(7x-3)
= 49x^2 -21x -21x +9
=49x^2 -42x +9
Answer:
x = 2/3
Step-by-step explanation:
Let's unpack the equation 
from our definition of 
:
(where 
)
Now that we've got things defined in terms of familiar operations, we can simplify and solve for x:
Answer:
95°
Step-by-step explanation:
It's a <u>pattern</u>:
<em>135,95,135,135,115,</em><em>95</em><em> </em>
The pattern is<em>...</em> 135, (95) then two more 135's then 115 then the pattern restarts.
I hope this helps!
