Answer:
11 units
Step-by-step explanation:
Let's do it this way:
Length = l
width = w
initial equation for area is l * w
We know that l = w+5
substitute.
w+5 * w = 36
solve.
6w = 36
w=6
The width is 6 units.
6+5 = 11
length = 11 units
It's 9. I just did it on Deltamath
The answer is attached.
x+1
Let's call the number we're looking for . We know that is twice as much as .
Twice as much as a number simply means the double of that number, and in turn the double of a number means to muliply that number by 2.
So, in order to obtain , you have to multply by 2. In formula, you have
or simply
(2, 2 )
Given endpoints (x₁, y₁ ) and (x₂, y₂ ) then the midpoint is
[ (x₁ + x₂ ) , (y₁ + y₂ ) ]
Here (x₁, y₁ ) = (A(5, 8) and (x₂, y₂ ) = B(- 1, - 4) , thus
midpoint = [ (5 - 1), (8 - 4 ) ] = (2, 2 )
