F(x) = x^2 + 24x + 138
f(x) = x^2 + 24x + (24/2)^2 + 138 - (24/2)^2
f(x) = (x+12)^2 - 6
It is 3468 Bc the other choices don’t make sense
Since we have (4,?) we know x=4. Substitute this into the equation and solve for y.
y= 2/7*4+3
y= 2/7*4/1+3
y= 8/7+3
y= 8/7 + 3/1
y= 16/14 + 42/14
y= 58/14 or 4.14
Expand and simplify LHS - Apply identity sin^2x+cos^2x = 1 To verify: (cotx<span> - </span>cscx)(cosx+1) =-sinx LHS=(cosx/sinx - 1/sinx)(cosx<span>+1)</span>
