Answer:
(x + 6y)(x - 3y)
Step-by-step explanation:
Given
x² + 3xy - 18y²
Consider the factors of the coefficient of the y² term (- 18) which sum to give the coefficient of the xy- term (+ 3)
The factors are + 6 and - 3 , since
6 × - 3 = - 18 and 6 - 3 = + 3 , then
x² + 3xy - 18y² = (x + 6y)(x - 3y)

3c+6=18 how do you work this problem?
Answer:
c = 4
Step-by-step explanation:
Simplifying
3c + 6 = 18
Reorder the terms:
6 + 3c = 18
Solving
6 + 3c = 18
Solving for variable 'c'.
Move all terms containing c to the left, all other terms to the right.
Add '-6' to each side of the equation.
6 + -6 + 3c = 18 + -6
Combine like terms: 6 + -6 = 0
0 + 3c = 18 + -6
3c = 18 + -6
Combine like terms: 18 + -6 = 12
3c = 12
Divide each side by '3'.
c = 4
Simplifying
c = 4
Answer:
Step-by-step explanation:
subtract six from both sides
3c+6-6=18-6
simplify
3c=12
divide both sides by 3
3c/3 =12/3
c=4

find the gradient of the line segement between the points (0,-6) and (2,-16)
answer = 5
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

Step-by-step explanation:
A new field has a perimeter of 220 m and a width of 62 m. A bag of canola seed will cover 185 m2 of ground. How many bags of canola seed are needed to seed the new field?
52
16
53
17
Answer:
17
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.

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.

What is circle?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.
