Answer:3/2

how i did this

​ Add 11 to both sides.

4x=5+1

Simplify 5+15+1 to 66.

4x=6

Divide both sides by 4

       x=   6/4

Simplify 6/4 to 3/2

       Awnser

x=3/2

Sorry if not helpful just trying my best :)

If the "discriminant" of a quadratic equation is -25, then the equation has _________________ solution(s).
slava [35]

no real solutions

The conditions for the discriminant are

• If b² - 4ac > 0 then 2 real and distinct roots

• If b² - 4ac = 0 then 2 real and equal roots

• If b² - 4ac < 0 then no real solutions

A cardboard box without a lid is to have a volume of 5,324 cm3. Find the dimensions that minimize the amount of cardboard used.
romanna [79]

The area of the box is

A(x,y,z)=xy+2xz+2yz

which we want to minimize subject to the constraint xyz=5324.

The Lagrangian is

L(x,y,z)=xy+2xz+2yz+\lambda(xyz-5324)

with critical points where the partial derivatives are 0:

L_x=y+2z+\lambda yz=0

L_y=x+2z+\lambda xz=0

L_z=2x+2y+\lambda xy=0

L_\lambda=xyz-5324=0

Notice that

L_y-L_x=(x-y)+\lambda(xz-yz)=0\implies(x-y)(1+\lambda z)=0\implies x=y\text{ or }z=-\dfrac1\lambda

Substituting the latter into either L_x=0 or L_y=0 will end up suggesting that \lambda is infinite, so we throw out this case.

If x=y, then

L_z=0\implies4x+\lambda x^2=0\implies x=0\text{ or }x=-\dfrac4\lambda

We ignore the case where x=0 because that would make the volume 0. Then

x=y=-\dfrac4\lambda\text{ and }L_x=0\implies-\dfrac4\lambda+2(1331\lambda^2)+\lambda\left(-\dfrac4\lambda\right)(1331\lambda^2)=0

\implies2662\lambda^3+4=0

\implies\lambda=-\dfrac{\sqrt[3]{2}}{11}

so we have one critical point at

(x,y,z)=\left(22\sqrt[3]{4},22\sqrt[3]{4},\dfrac{11}{2\sqrt[3]{2}}\right)\approx(34.9228,34.9228,4.3654)

which give a minimum area of about 1829.41 sq. cm.
