The polynomial that represents the area of the trapezoid shaped window is: 1/2(8x² - 14x - 15).
<h3>What is the
Area of a Trapezoid?</h3>
Area of trapezoid = 1/2(a + b)h, where a and b are length of the parallel sides, and h is the height.
Given:
a = 3x + 5
b = x - 2
h = 2x - 5
Thus:
Area of trapezoid = 1/2(3x + 5 + x - 2)(2x - 5)
Area of trapezoid = 1/2(4x + 3)(2x - 5)
Area of trapezoid = 1/2(8x² - 14x - 15)
Therefore, the polynomial that represents the area of the trapezoid shaped window is: 1/2(8x² - 14x - 15).

225/100
225 ÷ 25 = 9
100 ÷ 25 = 4
So, 225% as a fraction in it's simplest form would be 9/4
If you want 225% as a decimal:
225/100
225 ÷ 100 = 2.25
So, 225% as a decimal in its simplest form would be 2.25

Answer:
B)$319
Step-by-step explanation:
Interest each year is 275 × 4% = 275 × 4/100 = 11
total interest over 4 years is 4 x 11 = 44
total to repay after 4 years is 275 + 44 = 319
Normally you would divide something like this by the cuts made. So if there were cuts of 2 inches on a 10 inch rope, then you should divide 10 by 2. It's the same with this:
Multiply by the reciprocal when you are dividing fractions.
