Answer:

6\sqrt{5}

Step-by-step explanation:

In any right triangle, the Pythagorean theorem states:

a^2+b^2=c^2, where a and b are two legs of the triangle and c is the hypotenuse.

Plugging in given values, we have:

12^2+VU^2=18^2,\\144+VU^2=324,\\VU^2=180,VU=\sqrt{180}=\sqrt{36}\cdot \sqrt{5}=\boxed{6\sqrt{5}}

2x + 5y + 30 = 0 The point ( 5/2 , y) is a solution to the equation shown. What is the value of y? A) -7 B) -5 C) 0 D) 5
Zigmanuir [339]

Answer:

A) -7

Step-by-step explanation:

2x + 5y + 30 = 0

Let x = 5/2

Substitute into the equation

2(5/2) +5y +30 =0

5+5y+30=0

Combine like terms

35 +5y =0

Subtract 35 from each side

35-35 +5y = -35

5y=-35

Divide by 5

5y/5=-35/5

y = -7
