AB - C2 = (x2)(3x + 2) - (x-3)2
AB - C2 = 3x3 + 2x2 - (x2 -6x +9)
AB - C2 = = 3x3 + 2x2 - x2 + 6x - 9
AB - C2 = = 3x3 + x2 + 6x - 9

Step-by-step explanation:
The Hypotenuse of triangle, H = 25 cm
Base = 15 cm
Height = 20 cm
We need to find the area of the triangle. The area of a right-angled triangle is given by :

So, the area of the triangle is equal to
.

Step-by-step explanation:
sinθ = 63/√(16² + 63²) = 63/65
cosθ = 16/65
Using compound interest, the rates per compounding period are given as follows:
a) 0.1273 = 12.73%.
b) 0.0833 = 8.33%
c) 0.0617 = 6.17%
<h3>What is compound interest?</h3>
The amount of money earned, in compound interest, after t years, is given by:

In which:
- A(t) is the amount of money after t years.
- P is the principal(the initial sum of money).
- r is the interest rate(as a decimal value).
- n is the number of times that interest is compounded per year.
The <u>interest rate per compounding period</u> is given as follows:

For item a, the parameters are:
r = 0.12, n = 52.
Hence:

For item b, the parameters are:
r = 0.08, n = 104.
Hence:

For item c, the parameters are:
r = 0.06, n = 12.
Hence:
