4x^2-y^2 how do you factorize this? with steps pls:)

Answers

Answer 1
Answer:  (2x-y)(2x+y)

===========================================

Work Shown:

4x^2 - y^2

(2x)^2 - (y)^2

(2x-y)(2x+y)

When going from the second step to the third step, I used the difference of squares rule. That rule is a^2-b^2 = (a-b)(a+b). In this case, a = 2x and b = y.

Side note: (2x-y)(2x+y) is the same as (2x+y)(2x-y). We can multiply in any order.

9x+10=11x-10
Please show work

Answers

Answer:

[tex]x=10[/tex]

Step-by-step explanation:

1) Subtract 10 from both sides of the equation

[tex]9x+10=11x-10\\9x+10-10=11x-10-10[/tex]

2) Simplify

a. Subtract the numbers

b. Subtract the numbers again

[tex]9x=11x-20[/tex]

3) Subtract 11x from both sides of the equation

[tex]9x=11x-20\\9x-11=11x-20-11x[/tex]

4) Simplify

a. Combine like terms

b. Combine like terms again

[tex]-2x=-20[/tex]

5) Divide both sides of the equation by the same term

[tex]-2x=20\\\frac{-2x}{-2} =\frac{-20}{-2}[/tex]

6) Simplify

a. Cancel terms that are in both the numerator and denominator

[tex]\frac{-2x}{-2} =\frac{-20}{-2} \\x=\frac{-20}{2}[/tex]

b. Divide the numbers

[tex]x=\frac{-20}{-2x} \\x=10[/tex]

Simplifying
9x + 10 = 11x + -10

Reorder the terms:
10 + 9x = 11x + -10

Reorder the terms:
10 + 9x = -10 + 11x

Solving
10 + 9x = -10 + 11x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-11x' to each side of the equation.
10 + 9x + -11x = -10 + 11x + -11x

Combine like terms: 9x + -11x = -2x
10 + -2x = -10 + 11x + -11x

Combine like terms: 11x + -11x = 0
10 + -2x = -10 + 0
10 + -2x = -10

Add '-10' to each side of the equation.
10 + -10 + -2x = -10 + -10

Combine like terms: 10 + -10 = 0
0 + -2x = -10 + -10
-2x = -10 + -10

Combine like terms: -10 + -10 = -20
-2x = -20

Divide each side by '-2'.
x = 10

Simplifying
x = 10

Which is the image of the point (9,-4) after a reflection about line y = 2 then translated along the vector <-2,4>?
A. (7,4)
B. (9,8)
C. (7,0)
D. (7,12)

Answers

Answer: Choice D.  (7, 12)

=======================================================

Explanation:

Start at (9,-4). Move 6 units up to arrive at (9,2). This second point is on the horizontal mirror line of y = 2. We move another 6 units to get to (9,8).

Going from (9,-4) to (9,8) represents reflecting over the line y = 2.

Now apply the translation vector <-2,4> which says "shift to the left 2 units and shift up 4 units". That translation vector is the same as writing the rule [tex](x,y) \to (x-2,y+4)[/tex]

Applying that translation to the point (9,8) moves us to (7,12)

Answer:-12r+20=-4(3r-5)

Step-by-step explanation:

Pls mark as brainliest

Answer:

-4(3r + 5)

Step-by-step explanation:

To factor -4 out of -12r + 20, we need to find out what are the factors that can be multiplied with -4 to get a product of -12r and 20.

To get a product of -12, we must multiply -4 by 3r.

And to get a product of 20, we must multiply -4 by -5.

Therefore, the correct answer is: -4(3r - 5)
