The Equation for this is A squared plus B squared equals C squared. So this would become 3 squared (9) plus 8 squared (64) equals your <span>hypotenuse squared. When you add these together you get 73. You then must find the square root of 73 which is 8.5. The length of the </span><span>hypotenuse is 8.5.</span>

What is -3 - 9n= 42 I can’t be negative
maw [93]

If you were to correctly simplify this equation, the answer would be a negative.

The answer is: n = -5

Here's how I got my answer:

Step 1: Add 3 to both sides. Which leaves us with -9n=42+3

Step 2: Simplify 42+3 to 45. Which leaves us with -9n = 45

Step 3: Divide both sides by -9. Which leaves us with n = -45/9

Step 4: Simplify -45/9, to get your answer, n = -5.

How do I solve #14????
Tcecarenko [31]
All the measures in a triangle are equal to 180 degrees.

Let the unknown angle= x.

40+89+x= 180

Combine like terms.

129+x= 180

Subtract 129 from both sides.

x= 51

The angle is equal to 51.

I hope this helps!
