Find the value of x (equation A)

Find the value of z (equation C)

therefore
The total amount of money is equal to

The rectangle that has area 400 has width 10, so its length is 40.
A = LW; L = A/W = 400/10 = 40
The length is 10 + 0.2 = 10.2. The width is 10 + 2 = 12
The multiplication is 10.2 * 12
40.2 * 12 = 40 * 10 + 0.2 * 10 + 40 * 2 + 0.2 * 2
40.2 * 12 = 400 + 2 + 80 + 0.4
40.2 * 12 = 482.4
The correct answer is true. To maintain your body temperature, your body converts chemical potential energy into thermal energy. The human body converts the energy stored in the food into some other energy specifically thermal energy.
