Answer:
you need to give us the equation or we can't help you
Step-by-step explanation:
i'm sorry if this is not what you're looking for :(
It’s 3.9 because if you write out the metric system K H D L D C M. From milliliters to liters is three spaces so for the num. 3900 go backwards three spaces
Let x represent the length of the shortest side. Then the perimeter is
.. x +2x +(x +13) = 149
.. 4x = 136
.. x = 34
2x = 68
x+13 = 47
The lengths of the sides are 34, 47, and 68 ft.
The answer is C. because 1.5 is the height while x is next to it to show the multiplication of years to height
