C equals 17.5 you have to cross multiply to find what c is equal to
What is the question? It doesn’t show
So.... notice the picture below
now, we know what the "height" or "altitude" is
now, we also know the perimeter is 18cm
so, k + k + b = 18
or 2k + b = 18
thus
so... one can say that
and you can simplify it if you wish.. not sure you have to
Hi how are you today hopefully your well
First lets do the math...
-72 / -9 = 8
the reciprocal of a number is just flipping the number.
example : the reciprocal of 2/3 = 3/2.....the reciprocal of 6/7 = 7/6...and when u have a whole number, put it over 1...
so the reciprocal of 8, or 8/1 is gonna be 1/8 <==
or u could do it this way...
reciprocal of -72 / -9 = -9 / -72, which equals 1/8
