So first its 20 x 20 which is 400 so then the lawnmower does 80 per min so 80 x 5 and u get 400
35 has 4 divisors, hence two factor pairs: 1*35 and 5*7. Each corresponds to a set of perfect squares that differ by 35
One pair is ((35±1)/2)^2 = {17^2, 18^2} = {289, 324}
The other is ((7±5)/2)^2 = {1^2, 6^2} = {1, 36}

Step-by-step explanation:
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>How to determine the graph of the function?</h3>
The equation of the function is given as:
f(x)=3(2)^x -4
Set x = 0, 1, 2 and 3
f(0)=3(2)^0 -4 = -1
f(1) = 3(2)^(1) - 4 = 2
f(2) = 3(2)^(2) - 4 = 8
f(3) = 3(2)^(3) - 4 = 20
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)
See attachment for the graph of the function
