Equation for company a: y=20x+8
Equation for company b: y=24x+4
Company A would be cheaper for 5 loads of laundry, because it is $108 dollars opposed to $124 which is what company b would charge for 5 loads.
$32 dollars is saved by using the services of company A instead of company B to clean 9 loads of laundry.
X will be the speed of species b and 4x will be the speed of species a:
x + 4x = 180
5x = 180
x = 180 / 5
x = 36 m/h
If species b has a speed of 36 m/h, the speed of species a is 4 times that:
4 x 36 = 144 m/h.

Answer:
Step-by-step explanation:
Area A = 1/2 bh
36a^2b^4 = 1/2 × (12ab)h
Cross multiply
72a^2b^4 = 12abh
Dividing by 12ab
h = (72a^2b^4)/12ab
h = 6ab^3
