x2 - 14 = 51 so x2 = 65 and then x = +/- sqrt(65) = +/- 8.06
A=lw A= (8.5)(6) A= 51 inches squared
a=bh/2 51=3(h)/2 17=h/2 h=34m
(9/4)2 = (9/4) x (9/4) = (9x9)/(4x4) = 81/16 = 51/16

- 51 (negative 51))
x2 - 14 = 51 so x2 = 65 and then x = +/- sqrt(65) = +/- 8.06

2.82967176 square meters 86" x 51" = 4386 square inches = 2.82967176 square meters
a=bh/2 51=3(h)/2 17=h/2 h=34m
I literally just need the answer 😭
(9/4)2 = (9/4) x (9/4) = (9x9)/(4x4) = 81/16 = 51/16

-3x2 = 5 + 3x (add 3x2 to both sides)0 = 3x2 + 5 + 3x or3x2 + 3x + 5 = 0 (since the discriminant is less than zero, we have complex roots)x = [-3 ± √[(32 - 4(3)(5)]]/2(3)x = [-3 ± √(9 - 60)]/6x = (-3 ± √-51)/6x = (-3 ± i√51)/6x = (-3 + i√51)/6 = -1/2 + (√51/6)i orx = (-3 - i√51)/6 = -1/2 - (√51/6)i
