Answer:

(x, y) = (-2, -1) or (2, 1)

Step-by-step explanation:

Substitute for x in the first equation:

(2y)^2 +3(2y)y = 10

y^2 = 1

y = ±1

x = 2y = ±2

Solutions are (x, y) = (-2, -1) or (2, 1).

Why is it not possible to form a right triangle with the lengths 2, 4, and 7? *

puteri [66]

Answer:

No. The sum of 2 and 4 is less than 7.

Step-by-step explanation:

So, first, to create a triangle, the sum of two smallest sides have to be greater than the longest side, which is 2+4 = 6, and 6 is smaller than 7.

So, no, 2, 4, and 7 cannot create a triangle, to be exact a right triangle.

Hope this helps!!
