Solve (5 x/3) (5 x/5) =54

Mathematics
1 answer:
Phoenix [80]4 years ago
7 0

Answer:

-\frac{9\sqrt{10} }{5}, \frac{9\sqrt{10} }{5}

Step-by-step explanation:

(5*\frac{x}{3}) * (5*\frac{x}{5} )  = 54\\ calculate the product

\frac{5x}{3} * x =54 multiply

\frac{5x^{2} }{3} = 54 multiply both sides by \frac{3}{5}

x^{2}  =\frac{162}{5}  separate into two solutions

x = ± \frac{9\sqrt{10} }{5}

Quadrilateral LMNP has sides measuring 16, 28, 12, and 32.
Rus_ich [418]
To dilate means to make larger and when dilating a shape you make all sides go up by the same ratio not amount you don't just add the same number to each side. also I have to assume that the sides go in order for every answer. so to start you set up a ratio using the first side take the 16 from the instructions and put it over the first side in the first answer so 16/24 or 2/3 when reduced then take the second side from the instructions and first answer and set them up the same way 28/40 reduced to 7/10 now if these ratios were equal it would be the answer however because 7/10 doesn't equal 2/3 a is not the answer. do the same for all the answers and you will get c to be the answer
