Determine if the three given side<br> lengths form a right triangle.<br> 10 cm, 15 cm, 20 cm
antiseptic1488 [7]

Answer:

It doesn't form a right triangle

Step-by-step explanation:

According to the Pythagorean theorem, the area of the square whose side is the hypotenuse is equal to the sum of the areas of the squares on the other two sides.

a^2 + b^2 = c^2 by substituting the three values, 10, 15, and 20 you should get an equivalent value of the hypotenuse.

10^2 + 15^2 = 20^2

100 + 225 = 400

325 =/= 400

This is false.

Since this is not equivalent, it is NOT a right triangle.

Hope this helped :)

The formula for estimating the number, N, of a certain product sold is N = 8800ln(7t + 9), where t is the number of years after
arsen [322]
To determine or predict the expected number of sales after 2 years, we substitute 2 to the t of the givne equation.
                           N = (8800)xln(7(2) + 9)
                                N = 27,592.34
Thus, it is expected that the number of sales after 2 years is 27,592 units.
