HELP PLEASE WILL MARK BRAINLIEST TO BEST ANSWER

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

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.

Answer:

$927.12

Step-by-step explanation:

18.94×50 =$947 15%× 18.94=2.84 2.84×7 =19.88 947-19.88=927.12

Answer:

x>=6

Step-by-step explanation:

Answer:

3/4 inch by 1/2 inch (length - width)

Step-by-step explanation:

If 1/2 inch equals 8 feet on the scale drawing, this means that 1/4 inch on the scale drawing equals 4 feet, by dividing 2 on both sides.

The storage shed is 12 feet long, and 4 feet on the scale drawing equal 1/4 inch. By multiplying the scale of 1/4 inch = 4 feet by 3 on both sides, we get 3/4 inch = 12 feet. This means that the length of the storage shed can be represented by 3/4 inch.

Since 1/2 inch equals 8 feet and the width of the storage shed is 8 feet, the width can be represented by 1/2 inch on the scale drawing.

Answer:

The last one

Step-by-step explanation:

Because it tells you what y is

Answer:

Assuming its asking which is the easiest one to use substitution its the last one: y= 2x : x + y = 28

Step-by-step explanation:

Because y and x are already one opposite sides you can substitute y in the 2nd equation with 2x. So you'll get 3x = 28 so x = 9.333333334. Then you plug your answer for x in the original equation to get y = 18.666666667

Ang SAgot ay pukingina ka

Answer:

x=8

Step-by-step explanarion:

Step 1

multiply the parenthesis with the factor 3

6x+12=-36

now, subtract 12 from -36

6x=-48

and finally we divide 6 by -48

and are left with

x=-8

=>A linear pair is a pair of adjacent angles formed when two lines intersect.

==>>Since the angles' two lines intersect, it becomes linear.

===>>>Formula: [tex]a+b=180[/tex]

Answer:

the only one that isn't is SRT And TRU. all the others are linear pairs

Answer:

First we will find the surface area of the right triangle.

area of the right triangle=1/2*base*height.

now multiply it by 2 then we will get the S.A of both the right triangles.

Now, the other seems to be a rectangle,so find its area. And also the unseen side is a rectangle so find its area also .

And. now at the last. plus. the area of all the sides. you will get your answer. understand buddy.

Answer:

-x

Step-by-step explanation:

Note that when there is a standalone variable (such as the x in this example), it typically actually means 1x. (If it is -x, it will be -1x.) However, you do not write 1 in front, as it is presumed.

Subtract the coefficient of each terms:

1x - 2x = -1x

-x is your simplified form.

Answer:

three thousand, four hundred and forty-two, minus, two thousand and nine hundred and eighty-seven. :)

Explanation:

The two points (0,0) and (2,1) are on the line. Apply the slope formula to them to get the following

m = (y2-y1)/(x2-x1)

m = (1-0)/(2-0)

m = 1/2

This indicates that each time you go up 1 unit, you must move to the right 2 units.

Slope = rise/run = 1/2

rise = 1, run = 2
