The formula for finding the perimeter of a rectangle with length, l, and width, w, is P = 2l + 2w.

Perimeter of a rectangle:
P=2I+2W=2(I+w)

But if the length and width of a rectangle are both double, then we would have:
Length=2I
width=2w

Therefore, its perimeter would be:
P=2(2I+2w)=4(I+w)

the old perimeter was P=2(I+w) and the new perimeter is P=4(I+w)=2[2(l+w)]
There the perimeter is twice as great.

Answer: C) the perimeter is twice as great.

Write an equation in slope-intercept form of the line that passes through the point (-2,1) and is perpendicular to the equation
blondinia [14]
Let's convert the equation into slope-intercept form.

3x + 18y = 4
Subtract 3x from both sides.
18y= -3x + 4
Divide both sides by 18.
y = -3/18x + 4/18
Simplify.
y = -1/6x + 2/9

To make a line perpendicular, we need the slope to be the reciprocal of the other. Flip the denominator and numerator, and change the sign. We also have to change the b to make the line go through (-2, 1)

-1/6 to +6/1, or 6.

y = 6x + b

Input the x and y values and solve for b.

1 = 6(-2) + b
1 = -12 + b
Add 12 to both sides.
13 = b

y = 6x + 13

In 6-8, each table represents a linear relationship. Use the slope formula to find the slope or rate of change shown in each tab
dimaraw [331]

The slopes of the relationships are given as follows:

6. 5.

7. 1.

<h3>What is the complete question?</h3>

The problem is incomplete, as the tables are not readable, but researching it on a search engine, we find that:

  • For item 6, we have points (2,8) and (6,28).
  • For item 7, we have points (-6,5) and (4,10).

<h3>How to find the slope of a line given two points?</h3>

Given two points in the format (x,y), the slope of the line is given by change in y divided by change in x.

Hence, the slopes for each problem are given as follows:

6. m = (28 - 8)/(6 - 2) = 20/4 = 5.

7. m = (10 - 5)/(4 - (-6)) = 10/10 = 1.
