Answer:
1 4/7
Step-by-step explanation:
2/5 x 7/7 = 14/35
4/7 x 5/5 = 20/35
3/5 x 7/7 = 21/35
14/35 + 20/35 + 21/35 = 55/35
55/35 = 1 20/35 = 1 4/7
Hopefully this helps you :)

Answer:
Attached: The red graph is a graph of g(x) = -2x + 2
The blue grap is the graph of g'(x) = -x/2 + 1
Step-by-step explanation:
To find the inverse of g(x) = -2x + 2
First replace g(x) with y;
y = -2x + 2
Then take y to the right and x to the left;
x = -2y + 2
Solving for y gives;
2y = -x + 2
y = -x/2 + 1
Replacing y now with g'(x) gives;
g'(x) = -x/2 + 1
The graphs of g(x) = -2x + 2 and its inverse are attached.
thanks for free pints.........
Let's say each row has x desks and there are y rows.
We then know that x*y =25
We also know that x*2-5=y (number number of rows is five less than twice the number of desks in each row)
So we substitute: x*(x*2-5)=25
putting numbers out of the brackets:
2x*x-5x=25
2x*x-5x-25=0
(2x+5)(x-5)=0 (this bracketing is true: you can check it by expanding it:
2x*x-10x+5x-25
So that means that either x=-2.5which can't be : there can't be a fractional number of benches,
or x=5
so each row has 5 desks and there are 2*5-5 rows, or 5 rows.
I drew it roughly
All 4 sides are = sqrt20
Looks like a rhombus
