20.50+36.21=56.57
Twice can be said as x2 so
20.50 x2=41
Leaving 56.57 and 41
56.67+41=91.67

Step-by-step explanation:
The line will have the same slope as the given line, which is m = 3. Therefore, the equation of the line in its slope-intercept form is

Next we need to solve for b by plugging in the coordinates of the given point:

So the equation of the line is

Answer:
a=2/10 x85
=17cm
b.3/10 x 85
=25.5cm
c.5/10 x 85
=42.5cm
the shortest piece is 17cm
Step-by-step explanation:
The inverse for f(x)=2x+4 is f-1(x)= x/2 -2
