Let x be the original side length of the square
P=2(l+w)
70=2((2.5+x)+(2.5+x))
70=2(5+2x)
70/2 = 5+2x
35-5=2x
30=2x
15=x
Therefore, the original length of the square was 15"
Hope I helped :)
To solve this you need to do 68/85 which gives you 0.8, meaning it will be a 80%
The graph of the function f(x)=3(2)^x -4 passes through the points (0,-1), (1,2), (2,8) and (3,20)
<h3>What are exponential functions?</h3>
When the expression of function is such that it involves the input to be present as exponent (power) of some constant, then such function is called exponential function.
here usual form is specified below. They are written in several such equivalent forms.
The equation of the function is given as:

Set x = 0, 1, 2 and 3

This means that the graph of the function f(x) = 3(2)^x -4 passes through the points (0,-1), (1,2), (2,8) and (3,20).
