Suppose the length and width of the rectangle are doubled. What effect would this have on the perimeter?

Answers

Answer 1

Answer: The perimeter is doubled

Step-by-step explanation:

When you double the length and width you have 2l as length and 2w as width. The new perimeter is 2(2l)+2(2w)=2(2l+2w). This means that when you double both sides, the perimeter is doubled.

What is the point of homework? It just puts more stress on everybody so i dont get it......
whats ur opinion???????️

Answers

Answer:

Homework is needed for students to practice the material they are learning. The more you practice each new concept, the better you get at it, and the faster you do it. By practicing a lot, you also end up memorizing the way to solve problems.

Homework is helpful in moderation. Too much can be stressful, but small increments allow us to retain information for longer amounts of time.

Which equation represents the vertical asymptote of the graph?

Answers

Answer: A) x = -8

There is a hidden electric fence of sorts where the graph slowly approaches this vertical line but never touches or crosses it. It might help to draw in a dashed vertical line through -8 on the x axis.

A vertical asymptote occurs when a division by zero error happens. For instance, the equation y = 1/(x+8) has a division by zero error when x = -8 since x+8 = -8+8 = 0 is in the denominator.

In the diagram shown below, Points M, N and P are collinear. If MN = 3x-9, NP = x+1 and MP= 6x-22, solve for the value of X (Answer notation: x=__)

Answers

Answer:

The value of x is 7

Step-by-step explanation:

M, N and P are collinear means they lie on the same line.

Mathematically;

MP = MN + NP

Thus;

6x-22 = 3x -9 + x + 1

6x-22 = 4x -8

6x -4x = -8 + 22

2x = 14

x = 14/2

x = 7
