5/30-x = 10/30+x
5(30+x) = 10(30-x)
150+5x = 300-10x
5x+10x=300-150
15x = 150
x= 10 mph

The answer is Half of product of its diagonals which is option C .
Let d1 and d2 be the diagonals of the rhombus.
A rhombus can be defined as a special parallelogram as it fulfills the requirements of a parallelogram, i.e. a quadrilateral with two pairs of parallel sides. In addition to this, a rhombus has all four sides equal just like a square. That is why it is also known as a tilted square.
Area of rhombus using diagonals (A) = 1/2 * d1 * d2.
where ,
d1 = length of diagonal 1
d2 = length of diagonal 2.
Therefore the answer is Half of product of its diagonals which is option C.

Answer:
$17.48
Step-by-step explanation:
^^^^^^^^^^^^^
Multiply everything in the parenthesis by 3.
3x - 6 + 5x = 18
Combine like terms.
8x - 6 = 18
Add 6 to both sides.
8x = 24
Divide both sides by 8.
x = 3
Hope this helps!
