(fg)-1(5)=g-1f-1(5)​
larisa86 [58]

Answer:

<em>f = g/ g+1</em>

Step-by-step explanation:

Remove Parenthesis.

<em>fg - 1  x 5  = g  - 1  x f  - 1 x 5</em>

Cancel <em>-1 x 5</em> on both sides.

<em>fg =  g - 1  x f</em>

Simplify <em>1 x f</em>  to f.

<em>fg =  g - f</em>

Add <em>f </em>to both sides.

<em>fg + f = g</em>

Factor out the common term <em>f.</em>

<em>f (g + 1)  = g</em>

Divide both sides by <em>g + 1</em>

<em>f =  g/ g + 1</em>

a^2+b^2=c^2

10.7^2+30^2=c^2

114.49+900=c^2

1014.49=c^2

square it

m=31.9

2.20^2 + 21^2 = 841

29^2=841

yes the triangle is right angled !!!
