Which equation is quadratic in form?
olya-2409 [2.1K]

Answer:

6(x + 2)^2 + 8x + 2 + 1 = 0

Step-by-step explanation:

A quadratic equation has the variable with the highest power of 2

6(x + 2)^2 + 8x + 2 + 1 = 0  when foiled out it has the highest power of 2

6x4 + 7x2 – 3 = 0  power of 4

5x6 + x4 + 12 = 0 power of 6

x9 + x3 – 10 = 0  power of 9

Help me please I'm trying to get this donee​
balandron [24]

Answer:

The answer is 15.

Step-by-step explanation:

Plug in the numbers for the a and b values individually.  For the numerator, 5(6) is the same thing as 5 * 6 = 30.  For the denominator, 1/4^2 would equal to 1/16 and when you multiply it by 32, you will get 2.

To clear things up, the fraction should be 30/2 and your answer should be 15 as a result.

Abigail wrote the statements shown in the chart. . Statement. Description. . 1. If two lines intersect, then exactly one plane c
Lilit [14]

The <u>correct answer</u> is:


B) Statement 1 and Statement 2 are theorems because they can be proved with the help of appropriate postulates.


Explanation:


<u>Statement 1</u> is the Line Intersection Theorem. To prove this, we use postulates about having only one plane passing through any 3 noncollinear points. We would choose two points from one line and one point from the second; they would be non-collinear points and be in one plane. This also works choosing the points the opposite way.


<u>Statement 2</u> is the Point and Line Contained in Plane Theorem. Again, if two lines intersect, we can choose three points to define a plane. We have to prove that both lines are in the plane. We rely on previously proven postulates to do this.

Multiply and simplify.
katrin2010 [14]
ANSWER


8 {x}^{5}  {y}^{7}  {z}^{2}


EXPLANATION


The given expression is

2 {x}^{2}  {y}^{3}  {z}^{2}  \times 4x {y}^{4}  {x}^{2}


We multiply out to obtain,


= 2  \times 4 \times {x}^{2}  \times x \times  {x}^{2}  \times {y}^{3} \times  {y}^{4} \times {z}^{2}

Recall that,

{a}^{m}  \times {a}^{n} = {a}^{m + n}


We apply this rule to obtain,

= 8 {x}^{2 + 1 + 2}  {y}^{3 + 4}  {z}^{2}

This simplifies to
= 8 {x}^{5}  {y}^{7}  {z}^{2}
