800 + 60 + 3 + 0.1 + 0.04 + 0.001
That's 863.141 in expanded form.
So given a rectangle
sides are
_<u>x</u>_
x-5|__|x-5
x
the perimeter is 90 inches
perimeter is
x + x + (x-5) + (x-5) = 90
combine like terms
2x + 2(x-5) = 90
distribute
2x + 2x-10 = 90
combine like terms
4x - 10 = 90
add 10 to both sides
4x= 100
divide both sides by 4
x = 25
now to find the length of a side
x is 25
and x-5 is 20
to check and see if that's right:
25 + 25 + 20 + 20 =?= 90
50 + 40 =?=
90 = 90
Now to find the area
A = b * h
so
x * (x-5)
substitute
25* 20
500
The area of the rectangle is 500
Hope this helps :)
Answer:
1/2
Step-by-step explanation:
So lets go over what slope is.
The formula for slope is y/x
To find this, we can just count the change in y, and put it over x.
So lets see.
On the graph, we can count that y goes up by one, and that x goes to the right by 2.
So this means our slope is y/x, or 1/2.
This is our answer.
I hope this helps! :)
I included a visual of this as well!
