A polygon is a planar figure characterized by a limited number of straight-line segments joined to create a closed polygonal chain in geometry. The correct option is A.

<h3>What is a polygon?</h3>

A polygon is a planar figure characterized by a limited number of straight-line segments joined to create a closed polygonal chain in geometry. A polygon is defined as a bounded planar region, a bounding circuit, or both.

The sum of the two given polynomial can be done as,

(3x² - 5x + 2) + (5x² - 2x - 6)

= 3x² - 5x + 2 + 5x² - 2x - 6

= 3x²+5x² -5x -2x -6 +2

= 8x² - 7x - 4

Hence, the correct option is A.

Write an equation in​ slope-intercept form of the line that passes through the given point and is parallel to the graph of the g
Shtirlitz [24]

Answer:

The equation in the slope-intercept form is

y = -5x - 41

Step-by-step explanation:

The given equation in the question is;

y = -5x + 2

The equation of a straight line graph can be written in the form;

y = mx + c

where m is the slope and c is the intercept

From here, we can see that the slope m is -5

Since the line is parallel to the new line we are trying to write its equation, it means that they have the same value of intercept.

Hence, the slope of the new line is also -5

Now, we can write the equation of the new line as;

y = -5x + c

we need to get the value of c here however

To get the value of c, we need to input the value of x and y

From the graph, x = -7 and y = -6

Substituting these values, we have;

-6 = -5(-7) + c

-6 = 35 + c

c = -6 -35

c = -41

So the equation of the new line will be;

y = -5x - 41

Answer:

Numeric expressions apply operations to numbers. For example, 2(3 + 8) is a numeric expression. Algebraic expressions include at least one variable and at least one operation (addition, subtraction, multiplication, division). For example, 2(x + 8y) is an algebraic expression.

Solve for x in the equation x^2-10x+25=35
yKpoI14uk [10]
The left side of this equation is already a perfect square:    <span>x^2-10x+25=35.

Rewriting it, we get (x-5)^2 = 35.

Taking the sqrt of both sides,    x-5 = sqrt(35).

Solving for x:    x = 5 plus or minus sqrt(35)    (answers)</span>
