(x^2 - y^2)/(3x - 3y) = ?

Answers

Answer 1

Answer:

I don’t really know but I think you can get like (x-y)(x+y) = 3(x-y). And then you like do 3(x+y)(x-y)??

Step-by-step explanation:

Answer 2

Answer:

[tex]\frac{x+y}{3}[/tex]

Step-by-step explanation:

[tex]\frac{x^{2}-y^{2} }{3x-3y}[/tex]

use the difference of two squares formula

[tex]\frac{(x+y)(x-y)}{3y-3} \\\\factor out 3 \frac{(x+y)(x-y)}{3(x-y)} \\cancel out the common factor; (x-y)\\your answer is[/tex]

x+y/3

Write the equation of the line 1x + 3y = 6 in y = mx + b form.

Answers

Answer:

y = -1/3x + 2

Step-by-step explanation:

1x + 3y = 6

3y = -x + 6

y = -1/3x + 2

Answer:

[tex]y=-\frac{x}{3}+2[/tex]

Step-by-step explanation:

1x + 3y = 6

We want the y to be isolated, so we subtract x from both sides,

3y = 6 - x

Now we divide everything by 3, to isolate y

[tex]y=-\frac{x}{3}+2[/tex]

You are indeed correct, A=3

Step-by-step explanation:

To compute the perimeter of a rectangle, you add the length, l , and width, w , and double this sum.

This means you can find the perimeter of a rectangle by evaluating the expression 2 (1 + w ).
Use this expression to find the perimeter of a rectangle with length 30 and width 75.
210 (A)
135 (B)
180 (C)
107 (D)

Answers

Answer:

210 (A)

Step-by-step explanation:

Use the formula:

P = 2(l + w)

Substitute the values and find P:

P = 2(30 +75) = 2(105) = 210

Correct choice is A

Answer:

given length [l]=30

width[w]=75

perimeter= 2 (l + w )=2(30+75)=210

so

answer is A.210

x=37, Angle A is 74. Exterior angle B is 185

Step-by-step explanation:

I'm pretty sure this right but This is a triangle that is folded to the inside. This means that most likely there is a negative interior degree

angle. Using the interior theorem, we can add up all the non adjacent sides to find the exterior angle of the adjacent side. 79+2x+32=5x, 2x+111=5x, 111=3x, x=37. Then plug 37 in for x Angle A is 74 degree and B exterior angle Is 185 degree.

Answer:

Step-by-step explanation:

Answer:

Step-by-step explanation:

It is given that two lines are parallel, and hence the corresponding angles are congruent, by corresponding angles postulate. It is also given that the triangles in the photo share an angle, by the reflexive property, the shared angle is congruent. Hence one can use angle-angle to determine that the two triangles in the picture are similar.

Using this, one can set up a proportion with the sides. The ratios of any two corresponding sides are the same as any other two corresponding sides in the triangle, respectively, this is due to the corresponding parts of similar triangles theorem.
