ANSWER


The correct answer is option D.


EXPLANATION


The given function is



k(x)=-3x^6-0.7x+x^3



This a polynomial function. All degrees are greater than or equal to zero.


The coefficient being decimals does not disqualify it from being a polynomial.


The highest degree of this polynomial is 6.


Therefore the correct answer is D

Answer:

x = 9

Step-by-step explanation:

Simplifying

17x + -12 = 114 + 3x

Reorder the terms:

-12 + 17x = 114 + 3x

Solving

-12 + 17x = 114 + 3x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-3x' to each side of the equation.

-12 + 17x + -3x = 114 + 3x + -3x

Combine like terms: 17x + -3x = 14x

-12 + 14x = 114 + 3x + -3x

Combine like terms: 3x + -3x = 0

-12 + 14x = 114 + 0

-12 + 14x = 114

Add '12' to each side of the equation.

-12 + 12 + 14x = 114 + 12

Combine like terms: -12 + 12 = 0

0 + 14x = 114 + 12

14x = 114 + 12

Combine like terms: 114 + 12 = 126

14x = 126

Divide each side by '14'.

x = 9

Simplifying

x = 9

HACTEHA [7]

Answer:

119.43cm^2

Step-by-step explanation:

The computation of the area of the shaded region is shown below:

As we know that

= Area of the rectangle - Area of the circle

where,

Area of rectangle is

= length \times breadth

= 11\times 12

= 132 cm^2

And, the area of the circle is

=  \pi\times r^2\\\\ = \frac{22}{7} \times 2^2\\\\ = \frac{88}{7} cm^2

Now the area of the shaded region is

= 132 cm^2- \frac{88}{7}cm^2

= 119.43cm^2

We simply deduct the area of the circle from the area of the rectangle so that the area of the shaded region.
