Because, after 3 years 1500+(3*60) is 1680! Hope this helped! Brainliest is always appreciated.

The amount of interest is the increase in the account: $1680 -1500 = $180.

Simple interest is computed by
I = Prt
You have I = 180, P = 1500, t = 3 and you want to find r. Put the numbers in the formula and solve.
180 = 1500*r*3
180 = 4500*r
180/4500 = r = 0.04

Of course, you know that 0.04 = 4/100 = 4%.

The area of the given parallelogram is 120.

Step-by-step explanation:

Step 1:

The parameters needed to determine the area of a parallelogram are the base length and height.

The base length of this parallelogram is 15 inches while its height is 8 inches.

The area of a rectangle is determined by multiplying the base length with the height.

Step 2:

The area of the parallelogram $= (b)(h).$

Here the base length is 15 inches and the height is 8 inches.

The area of the parallelogram $=(15)(8) = 120.$

So the area of the given parallelogram is 120.

Which polynomial identity will prove that 65 = 81 - 16

steposvetlana [31]

9^2 - 4^2 = (9 + 4)(9 - 4)
So the polynomial identity used here is
$(x + y)(x - y) = {x}^{2} - {y}^{2}$
