how to find a factor

"Factors" are the numbers you multiply to get another number. For instance, factors of 15 are 3 and 5, because 3×5 = 15. Some numbers have more than one factorization (more than one way of being factored). For instance, 12 can be factored as 1×12, 2×6, or 3×4.

x²(x + 2) ‐ x(x + 2) ‐ 12(x + 2)

x³+2x² - x²-2x -12x -24

Answer:

72

Step-by-step explanation:

Answer:

x = 72°

Step-by-step explanation:

Its an isoceles triangle so both angles are 54°

Sum of angles in a triangle is 180°, therefore:

54° + 54° + x = 180°

108° + x = 180°

x = 180° - 108°

x = 72°

On a coordinate plane, point B(–6, 1) is translated to B prime(–3, –2). Indira uses these steps to find a rule to describe the translation.

Step 1 Substitute the original coordinates and the translated coordinates into (x, y) right-arrow (x + a, y + b):

B (negative 6, 1) right-arrow B prime (negative 6 + a, 1 + b) = B prime (negative 3, negative 2)

Step 2
Write two equations:
Negative 6 + a = negative 2. 1 + b = negative 3.

Step 3
Solve each equation:
Negative 6 + a = negative 2. a = negative 2 + 6. a = 4. 1 + b = 3. b = negative 3 minus 1. b = negative 4.

Step 4
Write the translation rule:
(x, y) right-arrow (x + 4, y minus 4)

Which corrects Indira’s first error?
Indira should have substituted B (negative 6, 1) right-arrow B prime (negative 3 + a, negative 2 + b) = B prime (negative 6, 1) in Step 1.
Indira should have written the equations Negative 6 + a = negative 3 and 1 + b = negative 2 in Step 2.
Indira should have solved the equations to find that a = negative 8 and b = negative 2 in Step 3.
Indira should have written the translation rule (x, y) right-arrow (x minus 4, y + 4) in Step 4.

Find the x- and y-intercepts of the graph of -x +y = 8. State your answers as
whole numbers or as improper fractions in simplest form.

Answers

Given:

The equation is

[tex]-x+y=8[/tex]

To find:

The x- and y-intercepts.

Solution:

We have,

[tex]-x+y=8[/tex]

Put x=0 in the given equation to find the y-intercept.

[tex]-(0)+y=8[/tex]

[tex]y=8[/tex]

Put y=0 in the given equation to find the x-intercept.

[tex]-x+(0)=8[/tex]

[tex]-x=8[/tex]

[tex]x=-8[/tex]

Therefore, the x-intercept is -8 and the y-intercept is 8.

Use the equation y=3x-8 to find y when x=8

Figuring out ratios is pretty simple. Example: If the ratio of soccer balls to baseballs is 3:1 that means there are 3 soccer balls for every 1 baseball. Notice how it says “soccer balls to baseballs” and “3:1” the first type of ball/object is the subject for the 3 and the second ball/object is the number for the 1. So when it asks the ratio of chocolate cookies to the whole box, you need to put the number of chocolate cookies first (25) and the cookies in the whole box (40). So now the ratio is 25:40. Simplify and make it into fraction form and the answer is 5/8.
