Answer:
The diagonals of all parallelograms do not bisect each other at 90 degree angles.
Step-by-step explanation:
To solve for x in terms of b, simply treat b as a number, and solve for x as usual: first of all, we expand the left hand side:

Subtract 10 from both sides:

Divide both sides by -2b:

This means that in particular, if we set
, we have

Answer: 
Step-by-step explanation:
Given: Perimeter of triangular garden = 
The sum of two sides of the garden = 
Perimeter is the sum of all sides of a triangle.
Third side = Perimeter of triangular garden - sum of two sides of the garden

The expression represent the third side =

Value of an expression 8<span>3
</span>in where 8 is the base number and 3 is the exponent.
To get the answer, simply multiply the base number as many times as the exponent says.
Since the exponent is 3 and base is 8, we need to multiply 8 three times.
=> 8 x 8 x 8
<span>=> 512 </span>
Thus, the value of the given equation 83 is equals to 512
to check if our answer is correct, simply divide 512 by 8 twice.
<span>=> 512 / 8 </span>
=> 62 / 8
<span>=> 8</span>
