Answer:

(x+9)(x+4)

Step-by-step explanation:

We wish to factor x²+13x+36 into the form of (x+p)(x+q) where p+q=13 and pq=36.

Factors of 36: 1, 2, 3, 4, 6, 9, 12. 18, 36

Notice that 9+4=13 as 9*4=36, which satisfies the values of p and q

This means x²+13x+36 can be factored into (x+9)(x+4)

Answer:

Step-by-step explanation:

Assuming the field is a rectangle, the perimeter is found through the equation:

[tex]P = 2l + 2w[/tex]

Since we know the perimeter and width, we can substitute and solve for the length.

[tex](220) = 2l + 2(62)\\220 = 2l + 124\\96 = 2l\\l = 48\\[/tex]

Using the length and width, we can find the area.

[tex]A = lw\\A = (48)(62)\\A = 2976[/tex]

The area is 2976 squared meters. We divide by the area a bag of canola seed can cover and round up if necessary to find the total number of bags.

[tex]n = 2976 / 185\\n = 16.09[/tex]

Because we need a whole bag in order to cover for the decimal area, we round up to 17 bags.

Slope, sometimes referred to as gradient in mathematics, is a number that measures the steepness and direction of a line, or a section of a line connecting two points, and is usually denoted by m. Generally, a line's steepness is measured by the absolute value of its slope, m. The larger the value is, the steeper the line. Given m, it is possible to determine the direction of the line that m describes based on its sign and value:

A line is increasing, and goes upwards from left to right when m > 0

A line is decreasing, and goes downwards from left to right when m < 0

A line has a constant slope, and is horizontal when m = 0

A vertical line has an undefined slope, since it would result in a fraction with 0 as the denominator. Refer to the equation provided below.

Slope is essentially change in height over change in horizontal distance, and is often referred to as "rise over run." It has applications in gradients in geography as well as civil engineering, such as the building of roads. In the case of a road the "rise" is the change in altitude, while the "run" is the difference in distance between two fixed points, as long as the distance for the measurement is not large enough that the earth's curvature should be considered as a factor. The slope is represented mathematically as:

m =

y2 - y1

x2 - x1

Answer:

2x + 3

Step-by-step explanation:

two sides measure (x-1) which gives 2(x-1) or 2x - 2

subtract 2x - 2 from 6x + 4 to get 4x + 6

4x + 6 represents twice the length so divide it in half to get:

2x + 3

Answer:

148.877 cubic meters.

Step-by-step explanation:

To find the volume of a cube, multiply the side length by itself 3 times (x^3).

Like this,

5.3 ⋅ 5.3 ⋅ 5.3 = 148.877

148.877 is the product.

Therefore, 148.877 is the volume of this cube.

Given:

In a triangle,

[tex]a=7,b=24,c=25[/tex]

To find:

Whether the given segments are the sides of a right triangle or not.

Solution:

In a right triangle the square of largest side is equal to the sum of squares of two smaller side.

[tex]c^2=a^2+b^2[/tex]                 (Pythagoras theorem)

Three sides are [tex]a=7,b=24,c=25[/tex]. Here, 25 is the largest side.

[tex]25^2=625[/tex]

Now, the sum of squares of two smaller sides is:

[tex](7)^2+(24)^2=49+576[/tex]

[tex](7)^2+(24)^2=625[/tex]

[tex](7)^2+(24)^2=25^2[/tex]

Since the sum of squares of two smaller side is equal to the square of largest side, therefore the given segments are the sides of a right triangle.

Step-by-step explanation: By working out the problem this is what I ended up with.

The solution is : D. XY,  is of the segments below is a secant.

A circle is a closed two-dimensional figure in which the set of all the points in the plane is equidistant from a given point called “centre”. The perimeter around the circle is known as the circumference.

here, we have,

we know that,

A secant is a line which intersects a circle at exactly two different points and leaves a chord on joining those two points.

again, we know,

A chord is a line which which terminates on the two different points on the circle.

and, we have,

Radius is the line joining the center to any of the point on the  circle.

we know,

Tangent is a line which crosses from the outer periphery of the circle touching at any of its one point.

we get,

Thus the secant in the given diagram is clearly none other than XY.

Hence, The solution is : D. XY,  is of the segments below is a secant.
