What is -5(-3r-3)=75

Answers

Answer 1

Answer:

r = 4

Step-by-step explanation:

-5(-3r - 3) = 75

Divide both sides by -5.

-3r - 3 = -15

Add 3 to both sides.

-3r = -12

Divide both sides by -3.

r = 4

Answer 2
-5(-3r-3)=75 is equal to 4

Explain howto use friendly percents to find 35% of 80

Answers

Answer:

Answer:

You would have to add two different percents to get to 35. You would need to add 25% and 10%. So, I would divided 80 by 4, which gets me 20, and divided 80 by 10, which gets me 8. If you add 20 and 8 together, that gets you 28. Your answer is 28.

Answers

Answer:

a) 6x³ − 5x² − 39x + 35

b) no

Step-by-step explanation:

(2x − 5) (3x² + 5x − 7)

Distribute:

3x² (2x − 5) + 5x (2x − 5) − 7 (2x − 5)

Distribute again:

6x³ − 15x² + 10x² − 25x − 14x + 35

Combine like terms:

6x³ − 5x² − 39x + 35

5x − 2 is the opposite of 2x − 5, so you would get the negative of the answer from part (a).

Which best describes the dimensions of a plane?
A plane has zero dimensions because it represents a location on the coordinate plane.
A plane has one dimension because it is made up of an infinite number of points.
A plane has two dimensions because it is a flat surface that has length and width but no depth.
A plane has three dimensions because it is made up of exactly three noncollinear points.

Answers

Answer: C) 2 dimensions; flat surface of length and width, but no depth

One way to think of a plane is to think of a flat sheet of paper that extends infinitely in all directions. The paper must be kept flat without any bends.

The statement that describes the dimensions of a plane is (c) a plane has two dimensions because it is a flat surface that has length and width but no depth.

To understand what a plane is, take a look at a flat surface such that:

PaperTop of a tableA white or black boardEtc.

Notice that the above surfaces have just two dimensions (horizontal and vertical).

This is so because they are flat surfaces, and they have no heights

Hence, the statement that describes the dimensions of a plane is (c)
