For what value(s) of the constant b does the equation f(x)=3x^2+bx+27 have 1 x-intercept

lions [1.4K]

Step-by-step explanation:

An a quadratic equation,

${ax}^{2} + bx + c = 0$

If the quadratic has one solution,

then

$b {}^{2} - 4ac = 0$

So plug in 27 for c, and 3 for a

${b}^{2} - 4(3)(27) = 0$

${b}^{2} - 324 = 0$

${b}^{2} = 324$

$b = 18$

$b = - 18$

So our answer is 18 or -18

Just find the figure of the rectangle plss

AnnZ [28]

Answer:

x= 21

y= 3

z= 21

Step-by-step explanation:

Let the center be O,

=> Triangle AOD is an Isosceles triangle so AO≅DO, "21 = x"

=> Line AC is divided in two equal parts by the center so if AO= 21 then

7y = 21, and thus "y = 3"

=> BOC is also an Isosceles triangle so CO ≅ BO, if CO = 21 (7y → 7*3) then so will be BO. Therefore "z = 21"
