I WILL GIVE BRAINLIEST TO WHOEVER ANSWERS FIRST!!!
Alex Ar [27]

Step-by-step explanation:

You want to set one of the equations equal to either x or y. For this, I put x+y=-2 equal to y which would be y=-x-2. Then you plug this in to the other equation for y. This would give you 5x+2(-x-2)=2. When you factor the two into the parenthesis, combine like terms, and keep the x values on ones side and the other numbers on the other side, you get 3x=6

If the lengths of the legs of a right triangle are 3 and 10−−√, what is the length of the hypotenuse?
Ganezh [65]

The required length of the hypotenuse of the triangle is √19.

<h3>What is a right triangle?</h3>
  • A right triangle, sometimes known as a right-angled triangle, or more formally an orthogonal triangle, formerly known as a rectangle triangle, is a triangle with one right angle or two perpendicular sides.

To find the required length of the hypotenuse of the triangle:

Legs in the right triangle refer to the perpendicular and base.

Hypotenuse:

= \sqrt{perpendicular^{2}+base^{2}  } \\= \sqrt{3^{2}+\sqrt{10^{2} }  } \\=\sqrt{19}

Therefore, the required length of the hypotenuse of the triangle is √19.
