15x + 4 would be the algebraic expression
Not completely sure what you are asking, but the area of a square with the side lengths of 230m would be 230*230=52,900.
A^2 - b^2 = (a - b)( a +b);
<span>cos^4x-sin^4x =( cos^2x + sin^2x )( cos^2x - sin^2x) = 1* cos2x = co2x.</span>
Answer:
Step-by-step explanation:
Let yesterday's price be x
Discount percentage = 36%
Sale price = $ 560
(100-36)% of x = 560
64 % *x = 560

Yesterday's price = $ 875
Are you trying to convert the percentages into fractions or??
