If x²+y²=106 and xy=24, find the value of 2(x+y)²

(×+y)^2 = x^2 + y^2+ 2xy

= 106+ 2×24

=106+48

=154

2×154 = 308

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116

cool stunts are flippin i think

sitting on a chair

and using stick feet
