Answer: 1 x 100, 2 x 50, 4 x 25, 5 x 20, 10 x 10
Step-by-step explanation:
Todos se multiplican a 100
(I don't know how to speak spanish that well, I'm assuming you asked what multiplies to 100)
We can set up an equation: x * (x + 5) = 564, where x is the length of the rectangle we are trying to solve. Using the quadratic formula to solve this, we eventually come up with approximately 21.38 as a value for x. We can verify this by typing 21.38 * (21.38 + 5) into a calculator and seeing that it approximately equals 564.
I = prt
420 = 7000 x .02 x t
420 = 140 x t
420/140 = 140 x t /140
t = 3 years
