Answer:
Perimeter: 6x+8
Area: 2x²+8x
Step-by-step explanation:
Perimeter- the sum of all sides
So, you do x+4+x+4+2x+2x
Simplify that to- 2x+2x+2x+8
And also simplify that to- 6x+8
Area- length*width
So, it's (x+4)*2x
which is 2x²+8x
Answer:
m = -1
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable.
m = -1
This question seems to have way too much information and be more confusing then it needs to be. When it comes down to it the only important information is that
<span>>The store manager decides to charge a weekly fee of $6

Answer:
tan(α) = 1/tan(90°-α)
Step-by-step explanation:
The tangent of one is the reciprocal of the tangent of the other.
__
In a right triangle, ...
tan = opposite/adjacent
For the two complementary acute angles in such a triangle, opposite and adjacent are swapped. That is the tangent of one is the inverse of the tangent of the other. (That inverse is also known as the cotangent.)
tan(α) = cot(90°-α) = 1/tan(90°-α)
