Answer:

$x = \frac {53} {45}$

Step-by-step explanation:

Step 1: Combine on the right side

$90x = 81 + 25$

$90x = 106$

Step 2: Divide both sides by 90

$\frac {90x} {90} = \frac {106} {90}$

$x = \frac {106/2} {90/2}$

$x = \frac {53} {45}$

Answer: $x = \frac {53} {45}$

Three zeroes in a fifth degree polynomial function are 1/3,4-61,and -2+11i

fomenos

The degree of the polynomial is 5, therefore are 5 zeros (real or imaginary).
The given zeros are
1/3, 4 - 6i, and -2 + 11i.

Because complex zeros always occur as conjugate pairs, the remaining complex zeros are
4 + 6i and -2 - 11i.

Answer: 4 + 6i, -2 - 11i.

Which correctly describes a cross section of the cube below? Check all that apply.

yarga [219]

A cross section parallel to the base is a square measuring 4 cm by 4 cm 

Step-by-step explanation:

Here we have to select the correct statement regarding a cross section of the cube :

A cross section parallel to the base is a square measuring 4 cm by 4 cm :

Since , every side of a cube is same . Any cross section of a cube must be parallel to a square base . Hence, correct statement .

A cross section parallel to the base is a rectangle measuring 4 cm by greater than 4 cm :

Since , every side of a cube is same . Any cross section of a cube must be parallel to a square base . Here, base is rectangle . We don't have a rectangle base in cube . Not correct statement.

A cross section perpendicular to the base through the midpoints of opposite sides is a rectangle measuring 2 cm by 4 cm:

Since , every side of a cube is same . Any cross section of a cube must be parallel to a square base . Here, base should be square not rectangle . So , Not correct statement.
