You have to find the common denominator*
Answer:
The length of the longest side is 68mm
Step-by-step explanation:
The perimeter of a triangle is equals to the sum of all its sides
P=a+b+c
The triangle is isosceles, so two of its sides are equal, have the same length.
So: a=b, then
P=2a+c=168mm
Moreover, we know that the base is 18mm more than each of the legs, this means: c=18mm+a, where we obtain that a=c-18mm.
So, the system of equations is solved, lets use the above result in Perimeter`s equation.
168mm=2*(c-18mm)+C
From here we have:
168mm=3c-36mm
We obtain the following result: c= 68mm, this the length of the longest side

Answer:
<h2><u><em>3484 </em></u>

</h2>
Step-by-step explanation:
<u><em>Given,</em></u>
<em>The figure is of a parallelogram</em>
Height (h) of the parallelogram = 52 ft.
<u><em>Since,</em></u>
<em>In a parallelogram opposite sides are equal so,</em>
Corresponding base to the height of the parallelogram is = 67 ft.
<u><em>Therefore,</em></u>
Area of the given parallelogram
= base × height
- <em>[On substituting their values]</em>
= 67 ft. × 52 ft.
- <em>[On multiplying]</em>
= 3484
<u><em>Hence,</em></u>
<u><em>The required area of the parallelogram is 3484 </em></u>
<u><em>(Ans)</em></u>
Answer:
f^-1(x)=x-14
Step-by-step explanation:
change f(x) to y :y=x×14
interchange variables :x=y+14
move constant(14) to the left :x-14=f^-1(x)
